MGH has wanted this for over 20 years and it hasn't meant squat.While I seem to always or almost always share your values, I typically disagree with you about how to actually get things done quickly (or at all). Here too I disagree. This becoming an "MBTA and MGH partnership" means one of the city's most powerful non-gov institutions now co-owns the project to a certain extent. It gains much more momentum that way.
BTW, values-based activism that has no chance of succeeding is failed activism. Humans are flawed, hey need unconventional pushes to get things done. That will always be reality.
