Seems to me Antifa was infiltrated when the video surfaced of them chanting for money. Could be that certain groups of them are being controlled by white hats that promised big money, trickled a little, then pulled the checks all of a sudden.
Same tactic was used by Q to gauge the response. Hype the arrests, activate the memes, then go silent. They can then monitor the reaction here which was negative but we survived as a group and are back stronger than ever.
