The point of the fediverse is to give people the option to create communities by themselves and not be subject to the ruling of one central allmighty entity. If someone does not like one community they have the chance to create their own with their own rules. This means people can decide for themselves what content they want in their community. However people coming from traditional social media seem to mistake this kind of freedom with not needing to follow any rules but that’s not how it works.
Lemmy.world is not frowned upon. There are some people who are very vocal about not liking it but if you don’t have any problems you don’t need to change. There is also nothing stopping you from having accounts on diferent instances so try some of them out and stay where you like it.
