I have nothing to hide, and I know the government and company monitor me
The issue is that there is a massive political correctness shift once people know they are being watched & judged (both in real life and on the Internet). Back in the 90s, it was the wild west. Napster & the RIAA tracking people was the first tipping point when it went from being do whatever you want, to your actions may have real life consequences.
My real concern is if Google or Facebook introduces a way to search the web looking for someone's face if you know their name. Not because I have anything to worry about. But because there are millions of naked girls on the Internet. They are fairly anonymous now, or it's like finding a needle in a haystack if you are trying to find a specific one. But if all of a sudden a Google search will bring up a girl's resume, and some nude pics that were taken 5 years ago at some college party, it leads to what the CEO said about changing your name once you reach 25 or so. I mean there is some reason that a lot of hot chicks are willing to get naked, knowing that their pictures and videos will make it to the Internet. I haven't figured it out because it has never happened in my life, but I see plenty of evidence that there are girls out there who are willing to get naked if their real life name isn't associated with it.
I also worry about some of the political and religious criticisms. Most people liked to be liked by their friends and family. And they usually would take the easy path of least resistance when it comes to arguing. On the Internet, you could really say what was on your mind, and it was real. If I have to sign my name on every on-line comment or download (and if my paycheck depends on having certain views), I would have to hold back on what I talk about.
