This is why the "cloud" model of AI is not really where I would want to be as a business.

Admittedly you are not going to get the same cutting edge performance, but I would only be basing a business on an AI I could download and run on my own hardware, such that at least current performance could be guaranteed going forward.

Anytime you buy anything as a service, you are in danger that due to malice, incompetence, lack of profitability, competing with a greater or established interest, or many other reasons, that service may become unavailable at little to no notice.

I don't understand why companies put themselves at these risks, when it comes to software as a service components to their business, when they wouldn't dream of exposing themselves to similar risks in any other domain related to their well being.

If you use it SaaS style and if you choose Llama or similar you are good. You can run it anywhere you can run a GPU. It is like using Linux on AWS. You get banned you can use Azure.
