I am as much anti sureveillance as you get. There is abdifference so between end-to-end encryption of communications (all for it) and collecting user data (all against it). Usually I hate semantics, because most of the time people use it to nitpick on deffinitiom ignoring what people understand using a word, but here the differwnce between the two things is a) technical reality and b) relevant for topic at hand.
Well encrypted data is practically useless to the collector. They could just as well be a random noise. Metadata may be worth something, but not nearly as much.
