I figured AWS would be the last to take a political stance like this. They're so low-level and ubiquitous I just didn't think they really cared. Not to mention the vast amount of spammers/scammers who get by with using their services and dirtying up the IP blocks. If AWS will kick a legal site, nobody is really safe in the cloud. Parler is probably going to need to go to bare metal servers or build their own private cloud.
