From Dave Winer.

today Twitter pulled the switch on two high volume Twitter clients, UberTwitter, the leading Blackberry Twitter client, and Twidroyd, which was the leading client on Android until Twitter shipped their own. Both are part of the newly formed conglomeration of Twitter client software in a $17.5 million tech/media company called UberMedia founded by Bill Gross.

I used to boast how Twitter was creating a coral reef which would support a thriving and diverse ecosystem. That was then, but now they’re running a stalag or gulag (a Russian variety of stalag). We don't know what Bill Gross and/or his team of developers did to piss off Twitter, which is itself a problem (the not knowing).
