I believe you are wrong , Dota2 was a rip off of LOL.
Interesting you mention the root kit - you realise Steam monitors urls Your machine has visited right? They also didn’t confirm whether or not these are then uploaded to their servers.
Dota 2 was a (almost carbon) copy of a DotA map for Warcraft III (there was even a settlement between Blizzard and Valve about this).
Not that it's necessarily a bad thing, but it makes more sense to claim that LoL was inspired by a DotA map.
