...I was trying to get worked up about the AWS plan to shut it all down. But, actually, I think it is a good thing. For one, they now join the ranks of Twitter as publishers and when the Section 230 protections go away, it hits them, too. Also, it WILL affect their business model. Who wants to sign on with them, knowing that if they take a dislike to your business model you can be axed in a matter of hours? I believe it may scare many away, even if they are woke leftists. It's creepy.
^this reinforces what I was getting at previously...
The hosting issue is simply one of money and resources - e.g. with sufficient funding, clarity of purpose, and skilled resources, it's possible to set up a new distributed cloud/hosting infrastructure & operations, with massive capacity & resiliency, from scratch, much faster than most would believe. I've done it before for clients (truly from scratch - i.e. empty buildings with no power/hvac/uplink/telecom preexisting), so this is not a matter of speculation...
And, with the shenanigans going on, the market disruption is likely sufficient to allow a new player to thrive. (I might consider building something myself right now if sufficient funding to achieve the required business velocity wasn't an issue.)
