I can't speak for SF I'm in Seattle. I don't think it is incumbent on delivery drivers to do activism for their employers. That's my opinion.

Someone else mentioned "externalizing" the cost of parking via citations. Those are expensive and a trove for the city. That sounds more like subsidising than externalizing.
As far as feeling sorry for "them" - that is a disconcerting view of a servant class.
UPS drivers don't need to write their congressperson. UPS the company can just get their lobbyists to pressure city officials to convert more street parking spaces to commercial only spaces.
