Maybe you would. The vast vast majority wouldn’t.
Not many people care about privacy from big tech, and those that do probably know what FOSS is and would know that they can trivially get Firefox for free.
I also doubt that Mozilla could get the hundreds of millions per year that they need to maintain a modern web browser engine, keep up to date on security, etc.
Wikipedia has a far wider reach, doesn’t have competitors in quite the same way Mozilla does, and needs far less money than Mozilla.
It takes hundreds of millions every year to maintain a modern web engine, have top-tier security, etc. It’s harder than maintaining an OS, even.
I just don’t see enough people getting in on that.
You mention Patreon. Alright, let’s go with that. The largest Patreon project by far earns less than $3m per year. Mozilla would need probably 150x that.
