I agree, what is wrong with calling it "privatization" or "enclosures"?
If the telephone were invented today, we'd be listening to ads instead of ringing tones.
It seems to me that capitalism reinvented itself over past 100 years by privatizing things that were either previously public or nobody could imagine them to be private goods. Aside from the military, utilities, copyrights (and fair use), attention and personal data, there are also various forms of consumer debt (mortgages). So I think it's important to put all these things into same context.
But it's a goofy term, and Doctorow is indeed annoying. Bird of a feather with this writer, whose style is also incredibly irritating. Nevertheless, good points worth making.
