I think Google is probably the most Free Software friendly of the the new big three (Amazon, Google, Microsoft). They haven't disappointed with Fuschia which appears to be entirely copyleft:
That's BSD-license though, which doesn't force companies to respect your freedoms. Parent was talking exactly about GPL being dropped in favour of licenses that allow vendor lock-in. It means a philosophical departure from user-first towards corporation-first and the Free Software world the FSF envisioned getting trampled.
The zeitgeist is moving towards conservatism in general, so it doesn't surprise me, but it's still sad.
Of the big three MS has definitely been the best lately, unlike the other too they've embraced open community development, not just open source. I still wouldn't trust them not to pull a bait and switch, but they've been better than the other two.
