How dare a vendor come up with an idea, pay people to execute on it, give it away for free to the world, acquire users and soak in all the community contributions from people who thought they were using and contributing to a public good, try and fail to indirectly monetize a hosted version because other people were better at it than them, then rug-pull out from under everyone and use copyright/government-stick to kill their competition because they can't compete on even terms.

Then a group of people who are users of idea and actually making money off it with value-adds step up to maintain it as a community project ensuring that it stays open for everyone -- yeah those guys are the assholes. Terraform would have went nowhere if it wasn't OSS and Terraform would be nothing without its outside contributions that make up far more than the code of Terraform core itself. There's a trail of bodies to prove it.

And you should love this, projects that are stewarded by its own users are incentivized to make it the best it can be instead of rejecting contributions because it competes with their cloud offering [1]
