For those of us who've been around for a while - as your reference to Slashdot points out - this can be surprising considering just how hated he was a decade or two ago when Microsoft was in a much different position than they are now.
I still have a negative opinion of him, and feel his business practices were extremely negative to the world.
But I will give credit to his ability to white-wash his image via numerous PR campaigns (Reddit AMAs, lots of other blatant social manipulation in the media). He and his marketing team have played the long game, and have been brilliant.
