Did any of those hearings end with a conclusion and solid evidence of collusion? How many of those companies or executives at those companies got convicted of market manipulation or conspiracy, or even charged?
Once again you are pointing to multiple independent companies, who are each other’s direct competitors, doing something at the same time and attributing that to collusion when there is no evidence for that at all. Is it that hard to imagine that multiple companies would decide at the same time to stop offering an app that harms their brand? Especially when those companies were getting heat because Parlor was used to organize the Insurrection and had many calls for violence? Also, are you now claiming that they previously colluded in support of Twitter but are now colluding against it?
You seem to have a tenuous grasp on…well, everything, but certainly reality. Companies do what they think will make them the most money. If all three thought that having Parlor on their app store, or ads on Twitter next to neonazis would make them less money than not doing those things, they would decide not to do them. It’s really really basic stuff.
