I think we (or at least I) have under-examined this: "Plans for future armed protests have already begun proliferating on and off-Twitter, including a proposed secondary attack on the US Capitol and state capitol buildings on January 17, 2021. " https://blog.twitter.com/en_us/topics/company/2020/suspension.html

This mentions a specific date! Twitter is telling us directly that their platform was being used for what sound like what could likely be terrorist attacks. If knew this and failed to act, how would people react on January 18? How much discretion did they really have in the ban?

Incidentally, I think Biden should make the inauguration all-virtual. We are in a pandemic, and the inauguration presents a high-value target. It's wholly understandable and good to not conduct it in-person

Adding to this thread with some of my more conspiratorial thinking: the fact that Google and Apple are dropping Parler from their App Stores out of the blue suggests to me that authorities have seen significant, worrying, imminent threats on that platform

This seals it for me. I don't believe for a second that AWS would kick a client off its platform for woke reasons.
I strongly suspect AWS knows future violence is being planned there and believes Amazon could be held liable https://www.theverge.com/2021/1/9/22222637/amazon-workers-aws-stop-hosting-services-parler-capitol-violence

No one wants a hosting provider that will pull out of a service contract. There's no public opinion upside for AWS here because AWS is mostly B2B, and those customers are counting on 100% dependable service they don't have to think about
