The problem is that nerds are allergic to advertising because they are allergic to "being sold to" because they (well, we) like to think we're above such petty foolishness.

As such we are not the customer. Therefore nobody cares what we think.

And privacy will go away.

The problem with this is, what happens if privacy goes away too much and somebody abuses it? What happens when a malevolent dictator takes over and oh hey look at all these devices so conveniently set up to spy on all the people. How wonderful. What if a benevolent dictator takes over but their idea of good doesn't align with your idea of good? What if somebody decides that oh hey, drunkness is a problem, people do terrible things when they're drunk, let's round up everyone who buys more than 3 sixpacks of beer per week and put them in a holding facility and fix them.

You know all those futuristic utopia movies that turn out to be a distopia under the hood? We're living in one of those. The question you're answering is whether you're inside the utopia or outside. Those of us who embrace the lack of privacy and being sold to, we're on the inside. Those like Stallman are outside.
