Twitter posted a note in support:

Every day, we suspend hundreds of applications that are in violation of our policies. Generally, these apps are used by a small number of users. We are taking the unusual step of sharing this with you because today’s suspension may affect a larger number of users.

We ask all developers in Twitter ecosystem to abide by a simple set of rules that are in the interests of our users, as well as the health and vitality of the platform as a whole.

We often take actions to enforce these rules; in fact, on an average day we turn off more than one hundred services that violate our API rules of the road. This keeps the ecosystem fair for everyone.

Today we suspended several applications, including UberTwitter, twidroyd and UberCurrent, which have violated Twitter policies and trademarks in a variety of ways. These violations include, but aren’t limited to, a privacy issue with private Direct Messages longer than 140 characters, trademark infringement, and changing the content of users’ Tweets in order to make money.

We’ve had conversations with UberMedia, the developer of these applications, about policy violations since April 2010, when they first launched under the name TweetUp – a term commonly used by Twitter users and a trademark violation. We continue to be in contact with UberMedia and hope that they will bring the suspended applications into compliance with our policies soon.

We can say it a war, and allegations of privacy violations and trademark infringement are serious. On checking History, UberMedia getting popularity by acquiring high profile Twitter clients for multiple platforms and devices.

Here is the, what Twitter sending to those users who are using these apps:

Dear xxxx,
