Also `sold` is a genius name.
All software should be free-as-in-freedom, but not nescessarily free-as-in-£; though I acknowledge that the former without the latter is often problematic. Plus, even beyond the "moral should", practically speaking, going non-FOSS this means it gets excluded from GNU/Linux distro packages, which IMO would be a fatal hit for something like this.
But honestly, I'm fine with this move. It's still FOSS for FOSS-systems, while support for non-FOSS systems is non-FOSS. The folks who care about free-as-in-freedom won't be affected by this. And even then, the non-FOSS `sold` is source-available, which covers 3 of the 4 freedoms; and IMO that missing freedom is the least important.
> I still suspect they won't succeed. How many businesses are so constrained by link times on Mac that they're willing to pay to reduce them? (And go through the admin effort of paying for something.)
A reasonable amount of software is "free-as-in-£ for personal use, paid for professional use." Lots of orgs are willing to ask individual devs "are there any dev tools you use that we should be paying for" and are willing to pay the $50/mo for IntelliJ, so $10/mo for `sold` seems to me like it stands a chance? Note that `sold` is still free-as-in-£ for use in CI/CD, and is only paid for individual-developer use.
I completely agree. If you believe "software should be Free!", then you're going to be using a Linux (or other FOSS) system, not MacOS. On top of that, Apple users are happy to pay through the nose for Apple products, plus apps in the Apple app store. Many studies have shown that app developers make much more money in the Apple app store than in the Google Play store, because Apple users love spending money on stuff, and Android users tend to be much more frugal. Apple users were the ones totally happy to throw away their wired headphones and rush out and buy $150 AirPods when Apple took away their headphone jacks. So this company is smart with this move: make the product a paid product for that group of users that has proven they're happy to spend lots of money on things. If anything, this company might have erred by not pricing it high enough to make it look like a luxury purchase.
Or maybe they are not as rich, since Apple is essentially a filter for "people who are willing to spend 700+ for a phone". Or they have more choices with better free/cheaper applications. Or they are able to pirate.
In the US, though, there's definitely a perception that Apple is for richer people and Android is for cheapskates.
But yes, it is a filter, which is why business tend to start out on iOS for early revenue numbers, and only port to Android a year later at the earliest. If you start out on Android, you'll inherently have lower revenue numbers, and spending time on your Android app is basically burning money when you're still in your Angel/Series A phases.
The relevant part of the EULA [1] states:
> Individuals who use the Software only occasionally, or non-interactive use of the Software that is not explicitly invoked by an individual such as CI/CD (continuous integration/continuous delivery), are not considered Active Interactive-use Users ("AIUs"). No additional fees are required for such uses.
I had to read it multiple times to understand the CI/CD bit. It's not clear to me whether the EULA says that CI/CD is an example of "use that is explicitly invoked by an individual" or if it's an example of "non-interactive use that is not explicitly invoked by an individual" - the wording is unclear to me and can have either of the opposite interpretations.
At my day job, we occasionally test C++ code changes by compiling in a CI/CD system to obtain a container image that we can push into a staging environment. This means we have a develop-compile-test cycle where the "compile" step involves pushing to a merge request branch, waiting for CI/CD to finish, and then running a deploy script to push out the newly-built image for testing. I wonder if this would be considered "Active Interactive-use Use" or not.

I agree that it’s hard to interpret, but isn’t the whole point of CI/CD that developers don’t start builds explicitly? For example, your example doesn’t mention it. You push to a branch, then wait for the build to finish, but never explicitly start it.
So, it seems they want to allow free use in CI/CD setups. Unfortunately, there are a lot of other ways to implicitly invoke the linker. Your typical IDE may already do that when you click “Run” instead of “Build”. I can easily see a lawyer argue that running make qualifies as explicit invocation, too.
> non-interactive use of the Software that is not explicitly invoked by an individual
...then we get "use of the Software that is interactive or explicitly invoked by an individual".
I would say that running make to run sold to run/test/ship an executable, or clicking "Run" to invoke sold and test the app, or pushing a branch to run CI that runs sold to obtain an executable to run/test/ship, all easily should be considered to be AIU - after all, in all cases it's a person clicking a button (or typing a command), waiting for it to run, and then doing something with the result.
For better or worse, iOS is not a niche target.
What's far worse than macOS not being a server OS is the hardware you're forced to contend with. Apple makes no server hardware. You end up with a disgusting hodgepodge of vendors making offerings that are largely redundancy in the way of massive falovers of mac minis. It's very unfortunate and makes self hosting or specifically (hardware or otherwise) needs extremely difficult.
Long link times are not specific to OS X / iOS. Large C++ codebases are some of the worst offenders and emit obscene numbers of relocations and DWARF symbols (or similar) into object files that bog linkers down. KDE, Firefox and Chrome browsers instantly come to mind. Rust and GHC generated object files also take a whiiiiiiiile to link[0].
On the businesses being constrainted by the link times subject more specifically. Über posted an article a while back enunciating the shenanigans they have to go through to build their iOS app (the app download at some point measured in a 300Mb+ vicinity): https://www.uber.com/en-GB/blog/how-uber-deals-with-large-io... . From the «Build Times» section of the blog post:
> The default pipeline builds the app in 21 minutes; the new pipeline with no machine outlining takes 53 minutes, which includes about 7 minutes of llvm-link, 14 minutes opt, 11 minutes of llc and 3 minutes of the system linker. One round of outlining takes about 7 minutes in llc, and 2 rounds take 9 minutes. Each additional round adds progressively less extra time, usually under 30 seconds. Overall, 5 rounds of outlining builds in 66 minutes — a 45-minutes addition to the baseline.
So, a default CI/CD build with no outlining heuristics applied spends 10 mins (7 + 3) out of a total of 53 mins in the linker. That is for a single CI/CD run.
And, since at least company has funded the work on fixing relocatable file generation in mold, there is indeed at least some demand:
> GHC (Glasgow Haskell Compiler) in particular uses re-linkable object files as dynamic libraries instead of real .so files, and it didn't work with mold. Now, mold can produce object files that GHC can load. Note that this work was funded by Mercury, so thanks to the company to help us improve the product.
[0] Fun fact: I have measured the memory throughput at the GHC linking time (via LLVM lld); it averages 65Gb/sec, and it can occasionally shoot over 70Gb/sec. So a faster linker still matters.
If it just works and I need to make sure I shell over the appropriate amount for our usecase it will already be easier.
If I need to pay up front to see how much real world gain we would get I am much likely not to do it. (Looking at you EE graalvm specifically now.)
Forget that for a moment. Economically speaking, there's tons of free competition and it doesn't have any real problems. That means the market price for a linker is $0. As you point out, people aren't going to pay for a faster one.
