It's all so strange. I would happily buy Firefox, either as a one off, or as an annual license, and be done with all the weird license nonsense - presumably they want to sell data to pay the bills. But instead the choice, realistically, seems to be between giving all my browsing data to Google and to Mozilla. And Chrome works marginally better... :/
Your framing that "the choice is between giving all my browsing data to Google and to Mozilla" creates a false equivalence. Even with their recent privacy policy changes, Mozilla's approach is structurally different from Google's core business model.
And "Chrome works marginally better"? By what metric? Firefox has better memory usage, stronger privacy protections, and doesn't exist primarily as a data collection tool for the world's largest advertising company.
The idea that you'd "happily buy Firefox" misses the point of Mozilla's mission for an open web. This kind of uninformed take that ignores the nuances of browser economics is exactly why we can't have nice things on the open web.
