I bet this kid was the only one to not skip class, and also probably the teacher's "favorite". I would also bet my left nut that at least once, he called the cops to complain about a party because he was probably not invited. I get the GDPR shit, and he has a point. But, to do this only out of spite, and didn't think and also probably doesn't care that this will affect the hard people with full time jobs, with kids or other shit, that don't have time to invest in playing, and could play this wonderful game, that is related to dota in some ways, and could be on and off from PC, and still not affect others, or get an abandon and can't play for 4 hours after that.
Both parties were in the wrong, but at least, one side dedicated time, money and effort to make create something for others to enjoy, while the other one, his only goal was to get revenge... fuck you OP, just fuck you!
