On apps that get acquired

But if it's open source, you can (FSVO "can", depending on your skillset) fix critical problems yourself.
Let's say I get Mailborg for $10 and move my mail over to it. Mailborg gets acquired. Dropborg eventually closes Mailborg. Next month, Apple releases OS X 10.12 and something breaks. I'm SOL.
Or I get open-source Thunderborg. Borgzilla stops development of Thunderborg. Next month, Apple releases OS X 10.12, and something breaks.
No matter. I'm still not SOL. Either I have a chance of fixing it, or more likely, someone smarter than me will find a fix and post it, maybe even with a new binary.
I'm no Stallmanite, but this is the whole origin myth of free software, for goodness' sake.
Open source communities also don't "just happen". It's pretty rare for someone to throw some code in a GitHub responsibility, wander off, and later find that it's suddenly become actively (or even passively) maintained.
Unless it's an app that's mission-critical to my life and there aren't any alternatives (even if they're not as good), I can't see myself digging in to fix bugs. And even then, it still feels like a hard sell.
I also feel like most apps that people might love enough to even consider diving into also have server components. If the company running the service shuts down, that's another barrier to setting up your own (assuming the backend pieces were even open sourced too!).
Sure, it happens, but those tend to be very very exceptional cases.
With closed-source/proprietary apps, you're at the mercy of the provider for getting out any data.
They can always end of life it after their last sale.
This guarantees the user that it's worth the time/investment, and the company can always decide to prolong the contract / expiration date.
Software (Best if used by X/XX/XXXX)
> There are some companies you can rely on: Bare Bones, Panic, and Omni (my employer), for instance.
Hmm. Panic killed its early MP3 player Audion not long after Apple started shipping iTunes in their OS for free [1]. And Omni has allowed their once mind-blowingly great web browser OmniWeb [2] to wither; though theoretically still in development, only "test builds" of the latest version have been available for years, and it doesn't even have its own page on Omni's site anymore.
The author's point - that software companies discontinuing software sometimes is a thing that happens regardless of other factors - still stands, but the companies the author cites as counter-examples are not themselves flawless.
