Not the point, but just for the sake of the argument, or lack thereof: first you stated they got banned because they broke the rules. Then when told that they enforced the rules differently to people with different political views, you claimed there was no evidence of such thing. And when confronted with evidence, you claim they can do whatever they want...
It is quite colourful to read you claim they could do whatever they wanted before because it was their platform but now come crying like a toddler when (as per your claim) they new owners apply the same criteria (i particularly disagree but hey, you're digging your own grave, not gonna stop you).
Some might call that incongruence. I find hypocrisy more fitting.
If you complain about the bias now and didn't before then your problem is not bias itself, it's the sort of bias you experience/d. Not quite the same.
