I agree with the whole section about containerization, which is especially important on the left where we have considerable efforts to undermine us at every turn, even here on this little forum where we don't actually "do" all that much. We by necessity have a system of trust based on account age and past-take-goodness because you have only so much time/attention/energy to spend on a particular subject that would be wasted on someone operating on bad faith or who is deliberately trying to waste your time.
I think you might be understating the risk of marketing agencies cooperating with state entities. I think intelligence works on the model of room 641A but even lazier, where they don't even store and sort data themselves, just have google do it for them. https://en.wikipedia.org/wiki/Room_641A
