Here’s the issue:
They offer a free public service to those who ride the public transportation system in San Francisco. It’s usually working all times of day/night, and anyone with a cell phone can take advantage of this public service.
They take away that service from law abiding citizens for the sole purpose of preventing an assembly of people for a lawful protest.
Maybe it’s just the liberal vs. conservative viewpoints, but in my humble opinion, taking away the free to anyone service for the sole purpose of preventing them to gather for a lawful protest, is unconstitutional.
