Point me to a particular comment, because as far as I can tell Occam's Razor suggests that if Google, Bing, and DDG are all returning the "computer" page on wikipedia for searches for "computer", then it probably isn't some sort of industry conspiracy to make Dell shell out more money to appear on the top, while also somehow involving small businesses... or whatever your personal angle is.

There is no reason to "follow the money" here because there is nothing here to doubt. It isn't fucking strange that wikipedia is featured so prominently.
