Are @Twitter and Free Speech Incompatible?

Free speech is not about agreement. It is a right protected for all in the United States Constitution.

A number of black groups, churches and activists from across America will gather in Los Angeles today to protest the NAACP Image Awards and accuse them of betraying the black community. 

They began by establishing a twitter account @NAACP_WATCHDOGS. This is a common use of social media worldwide. The NAACP complained and @twitter suspended the protesters account

Is it possible the NAACP does not want a twitter revolution?

Free speech advocates arise, turn on your laptops and other devices, you may be next.
