But they ARE honestly fulfilling the guarantee - the host is able to get the requested damages. Yes, it's not an unconditional, no questions asked compensation, but it's not advertised as such. Terms and conditions apply, just as it's reasonable to expect e.g. paperwork and evidence of damages before funds are released. It would be dishonest if they had included terms or conditions that are unreasonable or difficult to fulfil, but an NDA isn't such a condition; it doesn't disqualify anyone who wants to finalize the dispute. Just as it would be very reasonable if the release of funds was conditional on an agreement not to sue for further damages, i.e., that the guarantee happens only if it's agreed to be the final resolution of this matter.

The described events don't seem to violate any promise that was actually advertised, the only mismatch is between reality and wishful thinking.

You may think it is perfectly reasonable to have the customer sign an NDA before the warranty work or guarantee is fulfilled, but I find it dishonest and ridiculous.
