No. I never once saw anything like that. Some political stuff but 99% are conservatives anyway. No one(not many) to argue with.

I think pilots were getting into trouble with the company because company tools(scum of the earth) would send screen shots to mgmt. RLA stuff. Maybe some harassment. They claim, and it's probably true, that they were spending a lot of resources defending pilots in hearings because of The Line. That is, however, their job. I suspect that a lot of those hearings were from Facebook or other social media and were lumped in with The Line.

APA also got hit with some "official" pushback on censorship issues when moderators would remove stuff. Particularly from one very senior very well respected pilot.

The final straw was probably self preservation because a lot of card drive talk was happening. They suppressed threads titled "card drive" or something similar but the topics inside other, unrelated-to-card-drive, threads were most likely too much to keep up with. So they went nuclear and shut the whole thing down under the guise of "protecting pilots." They weren't going to allow that information delivery source to stick around.
