Its a comment from ProfessionalBox (a retired elite osu! mapper) on the map The Pretender back in 2017. The community made it into a copypasta and you’ll sometimes come across it in other maps.
I mean if you go and map The Pretender then what do you expect? It has such a big status as a turning point in the mapping meta that you can't avoid being compared. In my honest opinion there are songs that are tied to such grand maps that they should be given a status where they are not allowed to be ranked if mapped by someone else (The Pretender being one of them). That being said I haven't looked at the map so I have no opinion on it, because the quality of the map is irrelevant in this matter. This is about preserving history of osu! and therefore I hope that this doesn't become a trend in the future.
