Past sins, perhaps? I personally feel that Gates has done plenty to atone. But maybe others aren't so forgiving. I might feel differently if my company and livelihood had been destroyed by the heavy-handed tactics of 1990s Microsoft.

Are you actually willing to learn, to at least consider whether a statement is true based on the merit of the facts presented, or will you categorically deny any source that isn't directly connected to legacy media?
