Google hasn't been forbidden from paying Mozilla - yet, at least. They've only been ruled a monopolist, but what consequences they will face is yet to be determined, and then the appeals process will follow, so it'll be a couple of years before there's any potential impact.

Mozilla has also explicitly tried to have other baskets to put eggs in (Relay. VPN, Monitor Plus, Hubs, etc.), it's just that none of those have been as successful.
