One of my biggest issues is that the principles and ideas that come with the open source community are practically shutout by the use of discord. Information does not flow freely, it's locked in a server and it's not easily accessible by other people. It's not indexed by search engines. It might as well be missing completely. Half the time I plan to learn an open source project and learn that the majority of the discussion goes on in Discord, I already know that I'm going to have a horrible time finding answers when I need them so I just search for alternatives.
