Signature campaign managers just obey what their employer told them to do though so it's not a guarantee that it will last long or the company he/she working will be operating for weeks or months, it's not like that.
To an extent yes, but when a company contacts you you and that company discuss many things. At least you should IMO. You have the ability to tell a company how you feel about their plan, or you can shut, up tell them what you offer, and get paid. Those that are just looking for a paycheck are not the best managers IMO.
