"Actively collaborating" meaning doing the bare minimum to keep Google paying while actively fighting the bad things Google does everywhere else?
This is the rich philanthropists debate all over again. Yea, sure, they got rich from participating in the system, but they're using a big chunk of that wealth to fight its consequences. Sure as hell beats the alternative, where the only people willing to fight are the ones without the resources to do it.
I'd honestly rather see Firefox development be funded by selling NFTs and mining crypto, than not funded at all. Volunteer/donation-driven FOSS is great, but it has never been able to compete with for-profit products and it sure as hell couldn't compete with Google here.
But their marketing copy has a bunch of differently colored corporate Memphis people doing happy and fun things, surely they have our best interest at heart!
I'd be more convinced of this if they weren't actively collaborating with the big guys.
