It's a platform backed by a large company, it's bad for everyone (in the long term).

The much more problematic DRM and other walled garden issues aside, Steam's interface seems to be designed to emphasize safety, which would be fitting for software aimed at pre-teens, but is actually harmful for the teenagers and older that are its target.

(Of course one reason Valve likely did it is because it makes the job of their moderators easier - compare with the old Steam phpBB forums - and company-paid moderators is also the easiest moderation system to set up and maybe more importantly, remain in control of.)
