This already happens. Amazon is never the main contributor. That blog post talks about 33 commits for MariaDB for 2023. Like, that's great and all, but that project doesn't run on those 33 commits. It's the same with Elastic; when they did their license change I looked a bit at the commit history, and something like >95% was by Elastic.

And all these projects that did license changes are fine.
