I had some time to think about this comment, and I really like it. It demonstrates the issue underlying issue I was getting at with my original comment, but didn't express because it would not have come across as believable. I've encountered a lot in my career and has been the impetus for my last three job changes.

Hearing this tells me three things: you don't respect my work, you're publicly demonstrating that you're better than me, and that you're entitled to something from me for putting me in my place. Microaggressions like these are difficult to work with, no matter how much you're paid.

I'm sure you're a great developer, you've probably been promoted a lot, lead a big team and are generally well liked (at least on the surface). However, there are lots of developers and engineers that have been put down their entire lives and never really developed the social skills to stand up for themselves. Somehow, even over the internet, people like you can hone in on this and leverage it.
