His whole defense of the hosting company's hypothetical failure to help is bizarre. He considers a lot of things that aren't his concern or even really his business. A real analysis of whether to complain would only consider whether the hosting company will be responsive and whether they are competent to fix the problem.
Why is he considering—with incomplete information—the hosting company's legal options and the severity of the spamming?
Edited to add: He could also consider whether it is his hosting company with the problem or the orgs using UCEPROTECT; although as someone who needs their emails to go through "no matter what" that can be more difficult.
