Yea that is actually more a symptom of post-war generations, so isnt exclusive to OSS. Ask any employer how its going with their new young staff members.

but what I see causing far more problems in the OSS community is greedy patreon gatewallers who poach all they can from the devs, then put it behind a patreon wall and charge money for it. Them and corporate swooping in are a bigger problem than whining on a github issues board.
