Licence is MIT / Apache, of course.
EDIT: of course the relicensing is the problem here. Alas we’re in an all-time low interest in Free and Open Source politics, ideologies, and organization so the Big Evil Corpos continue to do their thing, one cog per time.
Permissive licenses also allow corporations to build off of open source software without giving anything back to public. I don’t see why they’re entitled to profit off the free labor of a community they don’t contribute back to.
While it does seem that way initially, strict copyleft licences can often do more harm than good. Projects need companies to use their software so that it becomes popular and get funding. There’s a reason why there’s barely any AGPL (or adjacent) licenced projects compared to GPL or MIT.
