Its one thing for neighbors to complain about loud and obnoxious people around them. Its a whole other thing for the police to preemptively break up shows. Some of the house spots that have been shut down in the past 6 months have been operating without complaint from neighbors for years.

Beyond that, the crackdown has been felt the most in the shutting down of art and show spaces in Allston warehouses which are zoned appropriately. Granted, the proprietors of these spots don't bother with permits from the city / following fire code, and often encourage or engage in illegal activity beyond simply hosting loud music, but these venues are definitely NOT disturbing neighbors (the neighbors in this case are generally rehearsal spaces for punk bands and other similar performance spaces).
