Sure - I agree that they get a benefit from giving us access to their tools.

In fact, if you ever can't obviously identify the benefit someone gets
from doing something, that's a good time to get suspicious.

This situation is a win/win. Even though Coverity benefits from
(hopefully, positive) publicity, we get access to tools that would
otherwise cost money that the project might not have, or might put
towards i.e. better hardware for project servers.

That's a good idea. I can summarize some right now.

A lot of the bugs found are allocation related: dereference of invalid
pointers, double frees or pointer overwrites - memory leaks.

Several of the ones I've looked at were in rare failure cases, so the leak
wouldn't amount to much, or happen often. That makes it easy to understand
why it hadn't been caught earlier - it never caused serious problems.
