Non-S&P500 corporations routinely violate open source licenses a myriad of ways.
If you license something as AGPLv3, Amazon, Microsoft and Google, among other S&P500s, will not integrate it into their service offerings.
Sherlocking happens to everyone big and small. If I work at Microsoft and see AppGet and make WinGet, what can the author do?
Microsoft will pay someone to reimplement X in C#, Google in GoLang, Apple in Swift, etc. etc. These aren't clean room implementations, but this is how they can consume code that is valuable to them.
If you have a speculative meeting with Google about working together, they may engage the quota-driven attorney to patent your work anyway (https://patentpandas.org/stories/company-patented-my-idea).
Let's say you contract to do work for Microsoft as a vendor, but you have "background technologies." That's fine, so you own the copyright to the code. If you make something innovative, your partner at Microsoft - some engineer or PM or whatever - will engage their quota-driven attorney to patent it. So even if contract X says you own the copyright to the code, they lie (by omission) and patent anything interesting anyway.
End users reading HN routinely violate copyright, EULAs, etc. I mean they believe in the rights of the author for AI generated art sometimes, do-not-train robots.txts, and then immediately use a paywall bypass or archive.lol to read an article written by a real human being. They complain about giant corporations violating these GPL provisions and then they go and pirate a video game, a movie, an anime, etc.
What is the cultural norm for stuff you put out there for the public on the Internet? It seems to be, tough cookie! If you purposefully put your stuff on the Internet (as opposed to someone buying something off X and pirating it), you've conceded: "If you have more money than me and if you never want to work with me again, I guess you can do whatever the hell you want."
There's an IP law crisis. We've totally abrogated IP law to capitalism. HN is part of the problem, people talking about laws, contracts, etc. that they themselves were routinely violate from Napster to What.cd, ad blockers, paywall bypassing like Archive.lol, etc. HN users excuse themselves just because the law says one thing, but is unenforceable unless you have a ton of money or something the counterparty has to lose, so you're going to do the norm, you're going to do the thing that you like that makes sense to you.
Nobody forces you to use RHEL or Rocky Linux. You can simply ignore this whole drama in this particular product category. But eventually, the giant corporations will simply copy your code and use it, and even if you have an open and shut case, you won't be able to afford a lawyer, you'll have to go beg. You'll get represented by the Berkman center for free, and you'll still lose. Something's gotta change.
