Mozilla is in a no win financial situation right now. The Google donations keep them running yes, but every time they try to diversify their revenue with things like sponsored content (that is still open source on the user side and deliberately has minimal analytics data and can be outright disabled), or their VPN, or whatever, their users raise hell even though it will help them get off Google dependency. Huge companiss use their other more significant-in-their-class products like Rust and they don’t get a dime from those companies, even ones that have large portions of their tech stack running it. They have a direct donation page, but if their public financial info is to be believed, almost no one donates.
