OK, except I’m not a Backblaze user and I never have been (except for the 14-day free trial). I haven’t had any private correspondence with them since reporting the vulnerability I discovered in 2019. This exchange on HN was the first time I’ve ever knowingly[0] interacted with this guy. If he has actually been ‘dealing with [me] for years’ in the way you imply, it has been a very one-sided relationship.

As far as having an axe to grind goes… if wanting to protect others is grinding an axe, I guess I’m guilty of that. I don’t feel like a handful of topical messages warning people of a legitimate and clearly ongoing problem is some abusive behaviour on my part, but maybe I’m wrong. I’m happy to learn from others’ perspectives, since I’m sure I could be a more effective communicator.

[0] I suspect he was the one who replied to my vulnerability report since the same attitude was on display in those messages too, but I don’t know since that account was just named “bbqa”.
