alt Hacker NewsAs a software engineer, I could not care less about how a bug was found or by whom, as long as I can quickly verify it is correct, I always appreciate being able to improve my work. I don't see why it should be different for mathematicians (the ones I knew would think similarly, I would assume.)
If I may offer an analogy, what I tried to do is essentially reporting a bug after having a failing unit test that exercises the public API, without looking into the black box of internals.
