One other thing I don’t see people pointing out is that Lemmy is basically a successor to classic web forums, so companies may run their own so they can have full control over the experience and moderation like for movies, series’s, or games, and in which case they would be more than happy to eat the cost of hosting. For example there could be a Lemmy.Disney.com instance to act as a Disney sanctioned discussion zone for their products where they could put tons of moderation rules in place.
Go to literally any other instance and create an account there
