I think it is reasonable to discontinue service if you don't like a customer.[0] But what if AWS's utility provider said we aren't going to power your datacenters because we like Parler? That seems wrong to me. I think it's reasonable to allow companies to terminate service but they should give a reasonable time frame (e.g. 3-6 months) to migrate to a new platform.
[0]: Certainly I think this in cases where you have a personal relationship with the customer/client, e.g. as a lawyer. It is less clear in the case where the service provided requires no real customer interaction as in AWS, where the services are all provided transparently, with no knowledge of who the customer is. But I don't want to get hung up on this issue.
In this case Amazon would likely apply pressure to the utility company's regulator, if such discretion was allowed to the monopoly provider under their current arrangements.
That pressure would likely be successful.
But even if a datacenter is removed from one jurisdiction, Amazon is perfectly able to handle that loss immediately.
