The issue as I see it is that once Meta or someone similar can start pointing to far right instances, child abuse materials or anything of the like and start painting Lemmy as a whole as the new 4chan “radicalising and grooming the children” only to release their “new app” which is just their instance then the “free fediverse” is going to BE the fringe.
Large companies will have no desire to be involved with “that place” because the sanitised, community guidelines having, data farming goliath will have 2 billion users. Why risk the bad pr?
