I'll be contrarian to the thread sentiment and say: Mozilla has misstepped in the past, and will continue to do so, and they're partially funded by competitors for antitrust reasons, etc.
That said, I can't really disagree with anything in this. As a developer (and socially conscious human) I want to move in the direction of openness.
I think the problem many of us have is it feels like Mozilla invests more effort into everything other than its browser, we see the things they do outside of Mozilla, I mean it was so bad Thunderbird had to become its own foundation due to lack of funding!
I would love for there to be a world where Mozilla maintains Firefox and can make for product projects that provide higher value. I also have a pipe dream of one day someone like (and if they read this, and anyone who reads this will think I'm crazy) CloudFlare just buys Firefox itself from Mozilla so it can finally be funded correctly. CloudFlare has an interesting talent pool and I'm sure there's people who work with Rust / have worked with Rust who can help fund something like Firefox. Then I would like to see them create a true open foundation whose entire bottom line goes towards Firefox, not to anything else.
Free the fox from corporate shennanigans. By my own corporate shennanigans. And CF could be swapped out with any company bold enough to free the fox.
