It's not "revisionist history", it's what happened. I was on Reddit for 3-4 hours each day and watched the entire thing very close. It was a way to show reddit admins who they're giving the middle finger to, and what reddit will look like when those people are gone. There's a reason it was called a "blackout" and not a "protest"... The protest wording only came up once the blackout had already started.
So really, the "protest" is your revisionist history.
