Why does every quake live player hide their steam game info (or private their profile) – From /r/Quake

I must’ve checked around 50 profiles of good players because I was curious to see how many hours they had played, every single one had their game info hidden or profile privated.

Edit: what made me ask this was because pretty much every quake player who i’ve played with and checked, has a private profile/private game info, which is disproportionately more compared to any other game. i know why people in general set their info to private, but i was wondering what it is with quake specifically that the players are always hiding their info. i just found it interesting.
