I’m afraid that Adam gets it wrong when he disagrees with Scoble and Israel in his piece entitled, "Disliking Microsoft". Industry enmity towards Microsoft dates back to BillG’s famous "Open Letter to Hobbyists" back in 1976.
There are two things that happened in the early-to-mid 1990’s that increased the negative perception of Microsoft. The first was the toppling of IBM — which up to that time had been the persistent bête noire of the computer industry — from its overwhelming position of leadership in the industry, creating an antipathy vacuum into which Microsoft fit nicely. To this point, I am reminded of the tired joke about the airplane in the fog in which the punch line is now Microsoft. When I was in college, the punch line was IBM.
The second was the uptick in political lobbying by some of Microsoft’s main competitors, namely Novell, AOL, and Sun.
