He’s just trying to help you, dude. lemmy.world is by far the biggest instance; 3x the users of the next biggest instance and much more than most. But, lemmy.world is also defederated from some notable instances like beehaw and hexbear. Another instance which also has in the tens of thousands of users (enough to be subscribed to “most stuff”) might well give you better search results.

You may decide that the defederated-from-here instances aren’t worth bothering with, with some justification, but you came in asking for help, he’s trying to help you, and you’re lecturing him about what’s what. 🙄
