Now is as good a time as any. The fact is the media will always be looking for the next Parler because it prints a great clickbait headline like "radical alt-right underground social network {discovered/deplatformed}".
Also they make great scape goats so people don't look closely at facebook et al.
I'm pretty sure a lot of the posts on facebook before the 6th also involved the insurrection.
Parler had 1.5 million daily users or so and I suspect a good portion of these were lurkers/observers and not users actively engaging in rebellion.
Zero moderation is not the way to go though, there needs to be mechanisms to remove posts with illegal material like child porn and the like or you risk blocking the whole network or make it "unhostable"
