Agreed. Embrace, extend, extinguish isn't a warning against Microsoft, it's a warning against a pattern of behavior that any corporation may attempt at any time it seems beneficial and likely to succeed. And it's a warning not about the first step (embracing a technology or standard is purely beneficial), but the second (extending it in proprietary ways for lock in). So keep an eye on every embraced technology of Microsoft and everyone else, and when you see someone extending it in incompatible ways, make sure you have an escape plan. The obvious example these days? Google Chrome.
