Reddit users who switched to Lemmy, what is the most annoying thing you have seen about Lemmy users?

The sheer number of FOSSholes.

Edit: seems like a struck nerve. To be clear, I'm not talking about the FOSS enthusiasts or enjoyers, they are A-OK. I'm talking about the FOSS fanatics who derive joy from trashing everyone else's choice of software and look for every opportunity to push their doctrine. They are the FOSSholes.
