Mozilla has lost the trust of its users by making decisions that their userbase doesn't approve of repeatedly, and then partially walking them back after the backlash.

That's not the fault of their users, at least not directly. If you want to argue that Firefox users are stifling innovation or trying to steer the product in a direction that would threaten the future viability of Firefox/Mozilla, I would be open to hearing that argument out even though I don't think that's the issue.

Mozilla is the equivalent of a petrostate in the tech sector. They have a bunch of revenue coming in that they didn't really earn, and they have no idea what to do with it to improve their current condition. To me, that's the core issue.
