> Gates's view was also that, once the market had sorted the good from the bad, Microsoft would, if desired, just implement whatever killer apps third party developers had discovered and make them part of Windows, cutting the floor out from under the third party developers. In other words, Gates viewed third party developers as doing market research for Microsoft that Microsoft didn't have to pay for.

Reminds me of how Amazon sees third-party sellers.

Maybe that is the standard abusive strategy of platforms that hold a dominant market position.
