I would chip in the average Facebook user value for my country if, and only if, Mozilla completely reversed course on ad tech, selling user data, and 'private tracking'. The fact that it acquired Anonym (with its close ties to Facebook) makes it clear that Mozilla would not diversify away from ads, it would just jump from one ad company (Google) to the other (FB).
I would not give a penny to a company that looks to sell me out.
