Protests work as a show of force (to the target of the protests) and to generate solidarity and increase numbers (for the protesters).
For them to actually work as a show of force, there has to be a credible threat of violence (or political action) waiting in the wings. All of the successful non-violent protests in the past had this. The idea is that you work with us on these reasonable requests or we put your heads on pikes. Without leverage, the protests are just a means of venting pressure.

These sorts of agreements are always so one-sided, also. What the company gets (tax breaks, property deals, etc) is always explicitly specified in the agreement but what the town gets (jobs, tax revenue, whatever) is left as unwritten assumptions, with the former never seemingly tied to the latter. If it wasn’t for the kickbacks and bribes, you’d think these towns were just really bad at writing contracts.
