In the very early days of Terraform, when it was 2 months or so old I helped a little. How many people did (so much more than me) with all these projects to be later betrayed by relicensing.

Were you betrayed? They did a thing you licensed them to do. That’s the whole point of non-copyleft free software licenses, after all! It’s kind of odd to specifically choose a license which allows others to use one’s code in proprietary software, then be upset when others use one’s code in proprietary software.
If one wishes one’s software and its users to remain free, the answer is to use a copyleft license.
They can and did use it in commercial software before relicensing. I don't have a problem with that. It's a betrayal to get a huge community together under one expectation and then decide you don't like that expectation any more. Had they used, even something like AGPL from the start it would not have been successful in the same way, would not have gotten the same levels of outside contributions, so yes it's a betrayal.
It's a limited betrayal, because that license also allows for OpenTofu to exist and fork, but the need to do that is just annoying.
