Fediverse

Meta exist to make a profit, however they're never going to be able to advertise to most people in the fediverse, who also happen to be some of the most knowledgeable people in some fields. If they accept that they're never going to be able to advertise to those people, they go for the next best thing: monetising their content. Some here may rightfully have an issue with a corporation monetising their content, however by federating with the fediverse and being the first company able to monetise the content within it, Meta have a vested interest in not extinguishing the fediverse.

Complain about their privacy violations or them monetising content they don't generate as much as you want, but remember they're smart & money hungry, and the smartest thing they can do in their position is to make money out of people they otherwise wouldn't be able to.
