The low visibility and low attendance aren't the result of any kind of management repression. I think it's a real change in sentiment. Most people don't care about this affair. Among people who are paying attention, there's a fair amount of internal skepticism and outrage fatigue. The small core group of habitual protesters is as active as ever, but they've struggled to come up with concrete evidence that substantiates their "systemic retaliation" narrative, and it feels like they've lost the hearts and minds of the public. It's telling that the main mailing list that these people use to communicate has enacted strict moderation policies that effectively ban debate and disagreement.
