Servers cost money to upkeep. So owners of big instances could start posting, ads, pin them and ban other users posting ads or delete their posts. This is obviously almost the worst case scenario. I feel that it wouldn’t happen in the near future, as Lemmy grows to become a larger platform. I haven’t seen this type of ads on Reddit so is there something stopping this?
I don’t see someone who uses the fediverse being open to ads and instead leaving for an instance that doesn’t have it. Reason being that blocking ads is also seen as a necessary part of secure browsing. A Facebook run one would do it, but I’m not using an instance or community that Facebook is running. I’d be using Facebook if I was fine with that.
