"I do nothing illegal, so I do not mind." is a terrible argument if only for the fact of being wrongfully accused. In court, evidence is used against you. Anything the NSA picks up can be used as evidence against you, whether guilty or innocent, to help sway a jury's decision on if you are guilty or not. If this doesn't scare you, google the people who spend over a decade in jail, only to be released later (some have died in prison). Lives are ruined, and for no good reason.

Yes, it can potentially save lives as well. But if I know government, or anyone with power, they will use that power. Especially when something doesn't quite go their way, and it's their ass or "some random guy". So your skype and facebook chats get pulled up and quoted in court out of context or whatever the hell it may be. But he magically never had skype...

I have many privacy fixes. Google Chrome extentions which block ads, remove "like this on facebook" or "post this to twitter" buttons from websites, and block websites who track which pages you visit. (If you use facebook and save your password, facebook puts a cookie on your machine that tracks what sites you visit, and then displays ads relevant to your interests based on what that cookie tracks.) Nothing stops them from tracking my IP, and IPs can be used to locate you physically.

I don't use my full name on youtube, but I'm sure many people here know my channel. All this shit, is ****ing private. Surely there are better ways that are safer and less invasive for innocent people becoming victims of corruptive abuse to catch da bad guys.
