It seems like there's at the very least a product-market fit for a cloud provider with less nebulous TOS. From the wording of the AWS contract, it sounds like the language is loose enough that any user can pretty much be terminated at whim.
If/when this lawsuit gets publicity, my guess is a lot of C-suite executives are gonna be looking over their shoulders and evaluating how screwed they'd be if their current cloud provider decided to deplatform them.
Amazon's probably counting on the fact that 99% of its customers' business doesn't have anything to do with politics, and therefore they'll write off the threat. But the counterpoint is that cancel culture has become so pervasive into people's personal lives that who knows what might happen.
If an executive shows up to a Trump-rally or posts a politically incorrect meme on his personal time, it's not outside the scope of possibility that AWS/GCP could demand that the company fire the person or else have their account terminated. The zeigeist is increasingly moving to the ideology that "silence is violence". Are companies, like Coinbase, that espouse political neutrality next?
Any company can now find itself on the wrong end of a cancel culture mob. If said mob has controls over your cloud providers TOS, then that's a major business risk.
