Thirty years, two CEOs, and at least two industry redefining tidal waves ago. The people who trot out Microsoft's HTML 2.0 strategy as a reason their work 30 years later is a trap, are deep in tin foil hat land and jumping at shadows.
Look at their wall street filings for the last decade. If Microsoft is running an elaborate EEE with their open source work, that first "embrace, extend" phase is now 10+ years in and responsible for an enormous portion of their bottom line with the fastest growth rates anywhere in the company. "Extinguish" would be suicidal.
One has to wonder if these same people also think Apple still secretly doubts the "think different" vision that Steve Jobs introduced in the same time frame, and could revert to beige boxes at any time. Or that IBM is really a hardware company and will drop services any moment.
