You missed one key difference, moderation, Parler straight up refused to remove these kinds of posts.

Parler just got ejected from the internet. Is it totally unthinkable that they would have adjusted their behaviour and moderated whatever Amazon had told them to if given, say, 2 weeks notice? They probably would have, then transitioned off AWS in an orderly fashion.

I mean, AWS basically took their business under false pretences. AWS wasn't trying to provide them a service, it was trying to kill their company.

Parler knew the terms when they signed the contract and didn't bother to adhere to them. They had months of notice. AWS did wait until Parler became completely toxic to enforce the terms, but they had lots of cause available.

Reddit has banned a lot of toxic communities over the years to avoid negative repercussions: https://en.wikipedia.org/wiki/Controversial_Reddit_communiti...

Same for Facebook and Twitter.

Parler, however, did nothing even as people went and publicly called out criminal acts happening on the platform.
