First, Steam are neither the publisher or developer. Unless it's an issue with the Steam version only, that Steam created (which is unlikely considering the nature of the problems) then it's not their fault. No one was blaming Gamestop for all the crap in Rage or Fallout or what have you.
In fact, three of your examples are audio, so probably an issue on your end. Check your drivers for new updates, check the forums for known issues with soundcards. Plus the most recent release you listed there is from 2004. 7 years old, you can't expect a game to work perfectly with todays hardware. If you're running Win7 then this isn't exactly surprising. Rockstar never release good PC versions, on Steam or otherwise.
It is quite likely these aren't common issues. KOTOR is infamous for being unreliable on new systems. If it's a driver/hardware issue, which it probably is, it's unfair to expect anyone to test every combination of OS and hardware. Have you checked the forums? Usually there's a fix for any problem you might encounter, and if you report the problem and Steam find out it's an issue on there end they might look into it.
