My normal attitude to sharing "inside" info on movements is that so long as it doesn't compromise safety of flight, the law or your sources... Spread the wealth. But, right now (and quite possibly next month) anything that attracts a crowd, or is seen as likely to attract a crowd, is going to get some people's hackles up, including some people who work at the clown show on the hill.
So maybe be discrete about anything that's not put in the public domain by the organisers? Not saying don't share, but maybe just don't share everywhere?
Opinions will doubtless vary.
