Thunderbird received close to $10 million in donations in 2023. And I’m willing to bet far more people use Firefox. If funding development directly, that’s not too shabby.
Wow, I honestly had no idea about that and you're exactly right, and everything I can see suggests that those were small donors to Thunderbird. It's hard to extrapolate, but it certainly seems like 10 to 20 million per year could be in play.
