No one said piracy is freedom of speech, but the sopa/pipa bills were to affect not only piracy, but other innocent sites as well. The right to flag and ban sites related to piracy was to be given to the american government which basically meant if once you get flagged you are guilty until proven innocent. That way the government can manipulate the usa public and ban domains similarly to the Chinese government! And that is how freedom of speech will be compromised. Ask someone from China if they know about the "thank man" or the students revolution itself. They may try to google it, but they won't find anything.
The management at DP don't usually make announcements besides ones that make them money, which makes sense, so I won't expect a word on SOPA. It just wouldn't be consistent with the culture at DP.
They're creating an alternate plan. The Open Act is a variation, and has support from sites like Google. Basically, they would block payments from US citizens, to foreign websites involved in piracy. It has criticism from artists that don't feel it's strong enough, but everything is still being debated.
As far as i know Lamar Smith has withdrawn the SOPA act to work on it more and find the mutually agreed act.
There should be more support from DP, but I guess it doesn't effect DP. I don't know why people haven't posted that many threads on it.
