They built their own gorilla cell network at one point.

Small correction of what I’m guessing is a typo, it’s guerilla rather than gorilla. Sorry for my pedantry.

I used the incorrect version of a similar word. Get over it. I could edit but now won't even bother.

They were trying to be helpful. Is there any wording of this kind of correction that you would have graciously accepted?

Nope, they were just trying to be right over a trivial spelling mistake on the internet. People that do that are the same people that others avoid at dinner parties.

I get that most spelling corrections on internet discussion boards are like that, but I don't think that's the case here.

It was a substantive error in the use of a whole word/phrase, and the commenter was trying to do you a favour by relieving you from that misconception for the future.
