"The problem with this is, do you want every program you ever use, to start prompting you with a series of questions about various opt-in / opt-out questions?"
Simple answer, Yes.
It would lead to conversations about the elephant in the room. It also alleviates the assumption I trust all providers(comprehend the EULA/ToS) and puts their actions under scrutiny. If more people realized what data is collected and by whom for whom they could make an informed, cost/benefit choice. Other useful results are, what is the applicability of that data to the project, what characteristics define the 'Trusted Partners' that data is shared with and, possibly, inject some restraint into the collectors' decisions of what to collect.
