Maybe it is to a child or average citizen, but I don't believe that "not understanding the consequences" is the case here on HN. This is just a difference in philosophy, the old "freedom vs. security" tradeoff that everyone falls down on a little differently. Giving up your data to a company (and therefore the government) in exchange for services is a trust exercise, and there are ways to avoid making it, but they have significant unavoidable costs. It's an easier decision when you don't fear your own government, but where you fall on the spectrum rapidly changes when your government makes you the target. Of course you can say "the government is always going to turn on you, so you should never trust them!", but you'll sound like a loon to many native citizens of a Western nation that have had little to fear for decades.

The US is just experiencing a little more of what the citizens of communist and fascist nations have experienced. Over time, that might lead to rapid societal change, or maybe it's too late.
