See gordyola's response, which maybe inadvertently shows how easily things might run away with themselves online, and lead to misplaced speculation and get amplified by social media etc.
In some ways, damned if they do damned if they don't, Sisk.
If they don't try discourage everything discussed at the events being shared, then they'd likely be far less open about things, more cagey in discussions, and generally guarded. Then the people attending the events suffer and come away thinking it wasn't very open.
If they do suggest people don't share, but then openly discuss and engage as it sounds they have, then others think why all so secretive.
As I said, I don't think they will come after anyone, and I don't think they would necessarily be bothered with people sharing certain gemeric discussions etc. But I'm more than happy to respect however people apply that.
They will also know fine well people attending will discuss it with close friends and family, in the pub, in person etc. Maybe even show images in person in private chats etc. Their issue is more likely to be it being put on general social media and snowballing out of control from there.
