Stopping/deleting nodes and paying for the previous month

I mean, why not?. Let the company know why you are shutting down 40 nodes.
Let other maybe potential SNOs know. Vent. I am fine with that.

At least what they were saying is that Vivint was so happy with the test results that they signed the contract. Should be good for anything then, at least not worse than a Wasabi or Backblaze data center somewhere, if we put certificates off the table.

It should be. It is their signature product and at least it was said that they do not advertise Select pro-actively to customers. But I agree that the missing complinace certifications for the global network might be a burden. There is also no statement if there is progress on that issue.
