The insight there is that one should always try to wrap criticism with praises: people don't like being told that they suck at their job, even if it's true. If instead of showing themselves as destructors, they'd adopted an image of mentors or teachers, things would've gone way better. Hopefully Google's Project Zero will be wiser than the IBM team on this point.
Note that this is even truer when criticism comes from an outsider, and Google's team will be doing exactly that. If they also deal with companies whose culture is very much reputation based (like in Asia), they'll have to be even more cautious.
