Android Not Open: No XMPP, No Source, No SDK For Some.
"Android started as an idealistic open source platform, with a large number of hardware manufacturers lined up supporting it. It is now becoming just a Google platform for mobile, as forcing Gtalk on developers has a chain effect of enforcing Google ID’s on users and all communication to pass through Google servers. Developers are becoming increasingly frustrated by first denying Android SDK updates to some and now by closing up and deciding what can and can’t be done on the platform. Instead of being an open platform, they seem to want to funnel everything through Google services."
