MassPIRG, and all of the PIRG groups, are ACORN-type operations.
I went to school in MA. One of my favorite pastimes was to annoy the MassPIRG students who always seemed to have a table set up in one building lobby or another looking for members, signatures, etc.
One day they advertised that would be set up outside one of the main academic building the next week for some global warming/high speed rail thing. It snowed. They were forced to move inside. All they could ever do was rattle off the MassPIRG provided talking points. If they didn’t have a talking point they would stammer and ignore you.
