As someone else pointed out cooler heads and less passive aggressive responses would've resolved this issue easily.
Honestly, it seems like both of you were feeling a bit "grumpy" at the moment, but sending passive aggressiveness towards the maintainer you are trying to get to merge your code (or not your code, someone else's code?) seems like a very bold strategy regardless.
But that doesn't negate the maintainer talking to people like that (and taking contributions without attribution).. and the net result is I don't want to use the software, and frankly they probably won't miss me.. so the end result is neutral.. I just find it sad.
Quite sure most (perhaps >99%) adult people would consider this passive aggressive.
But yeah, I agree with you for the rest part. Why did Mario assume that bot is you...?
