It's not like their original comment is that opaque, but here's my attempt to break down (translate?):
Are we going to continue to allow capitalist enterprise to have a say in public policy conversation (concessions stands outside the town square)?
Ideally no from an ethics perspective, but then we as a populace need a way to and habit of contributing directly ourselves to fund social services ("dropping a dollar in the plate" - reference to collecting tithe during Catholic services).
They're tired of seeing public services starved of funding, then privatized and replaced by corporate, profit-driven ("plastic") replicas.
Basics of human nature keep undermining our attempts to build giant organizations together. We need to make and keep government a local, small-scale, accountable practice we all participate in, rather than one giant federal tent nobody is connected to - that gets Orwellian.
Hope that helps and hope I represented it faithfully.
