Yes but not so much. The fediverse is a big place and everyone can open a community in the same topic in a instance that is not block. Look how many zero waste there is !zerowaste@lemmy.ml !zerowaste@slrpnk.net !zerowaste@lemm.ee !zerowaste@lemmy.world !zero_dechet@jlai.lu. And they may be more on instances I don’t know.
For what I have witness instances blocked each other over divergence on political activism. If you don’t plan to go discuss with people who really want to convince you to become communiste, you should be fine.
Go on [your.instance]/instances for the list of block instances.

Only insofar as some instances block communication from some other instances. Not mine though, that’s actually one of the reasons I picked it. That and it being by an org that’s older than the web and runs a public unix server and a bunch of retrocomputing type services as well as fediverse stuff. They started out as a dialup anime BBS.
