The reality is that this sort of control would only be attractive to a very very small fraction of users, and no, not just because ‘people don’t care about privacy’ or whatever. There are just very few situations where someone is going to be able to look at this sort of data and do anything meaningful with it, especially when a) most apps are justifiably internet-connected, and b) the homogeneity of public cloud infra means you can’t really tell anything apart from endpoint alone.
