Yes. They
apparently used code from an open-source project by a group of developers calling themselves Enormego. A little bit of controversy over that, but not related to patent infringement.
However,
the patent issue may still manifest itself:
If you do use this [code], be mindful that there is a patent pending for the concept:

Interesting, I know Tweetie did it best, not sure it did this first. Also to note that this question was asked well before the patent was even filed. – Daniel Mar 21 at 11:58
I believe that when the patent is filed is irrelevant. The criteria is "when did Tweetie 2 release this functionality," and "did anyone else release a product that did the same thing before them?" – Greg Maletic Mar 30 at 21:45
