Honestly, I'd much rather have the second opinion from the mayo clinic. If it could save me from an unnecessary spinal surgery (and all the issues that go with it) vs other effective medical treatments, I'm all for it.
Quite often, surgery isn't the best option but is still what surgeons opt for.
A quick google search finds this:

Sure, why wouldn't the company want to save money if it's not even needed for effective treatment? If it helps you why not? If it keeps my insurance premiums down, why not?
Sounds more to me that you like getting upset for the sake of being upset, especially when it's the Mayo Clinic and not some fly by night dr.
