That's not it, Mozilla decided to leave the fediverse and has been loading Firefox with AI and opt-out tracking features. All while still being funded by Big G.
I'm assuming they left the fediverse because it ended up not being a huge success, and not because they suddenly pivoted against decentralization.

did they? their mastodon instance at mozilla.social still seems to exist.
They recently announced that it'll be shutting down.
