The harder part, is getting non-tech people to join your boycott. Good luck trying to tell people not to see the new Batman movie when it comes out.
What would be good to know is if actors, directors, and other movie makers support the MPAA's actions. With the RIAA, you could sense that musicians often were at odds with the record companies that signed them. Is that the case with movies? Are there movie studios that don't support things like SOPA and PIPA? Maybe we'd have something if those people (if they exist) spoke out publicly against the MPAA.
