Right. Embracing the open standards - like they did previously (e.g. with GTalk), and then suddenly..."oh look, we've improved the standard, and we're not publishing our extended version. It's so much greater, but only works with this one client, made by us - what a coincidence."

Gee, I wonder where I saw this pattern before...nope, it's not like they're going to exterminate their Official Blessed Client once they tire of it, 18 months from now.

Surely with that attitude they're damned if they do and damned if they don't? If they make their own standard it's bad, but if they adopt an industry standard they're probably going to ruin it, so that's also bad?

If they've embraced an industry standard previously, extended it and exterminated, multiple times before, surely it will be different this time.
