I don't much like steam but you make a good point that it's rare for companies let alone CEO's to admit fault and compensate for it, without being forced by the law that is, so kudos to valve for that.

Now if they only also apologized for pointlessly ruining games with ingame ads and for having a support forum that's puritanical and overly - what I would describe as - 'fascist' in banning people that criticize them even when such critique is without a doubt correct.
