you guys aren't very in-touch with what's going on in the smogon community if you think it's just "finch/bkc lost to it and now they're angry", not saying it's necessarily a good ban but the use of king's rock fucking exploded during OLT (smogon's big on-ladder tournament) and has won a lot of high-profile games there
>https://replay.pokemonshowdown.com/gen8ou-1372539499almost 2000 elo game where a player running two king's rocks wins. you bet there's a lot more people yelling at the council to get rid of this than just finch or whoever, because 'cheese' like this always explodes in popularity (and visibility, literally more people spectating random ladder games and seeing this) during OLT.
i don't really understand why natdex got rid of quick claw too since that's not really a pervasive issue anywhere else but idk who plays that shit anyways
