I wouldn't worry about this unless they start forcing you to log onto these services in order to use the Internet. Facebook is an optional layer and isn't where I would go to get my news, it's where I get news about friends and acquaintances.

If you dislike this filtering simply don't log in to Google, or use Dogpile - also not logged in. They may still filter based on your country (ip address, etc.) so use a foreign search engine if you can read the language. Google can attempt to translate whole pages.

You can also use Tor , which picks an IP typically not from the US and anonymizes your session. You can also use Private browsing and cooky filtering in your browser to limit some other things....

I personally use news feeds from reputable sources and people (blogs) for all my informational needs; I haven't noticed it being filtered to cater to me, because I catered it! Twitter and Facebook are useless for news and it scares me that journalism is slowly dying to be replaced by a bunch of idiots with an opinion being taken as authority on day to day happenings. Don't get me wrong, it's a good place for opinions and discusions on current events and can even be a vehicle for reputable news sources, but it's not really a news tool!

Ultimately, everything you do can be tracked and compiled by your host regardless of the tools you use online to limit this "personalized" or "filtered" web. Everyone is capturing and storing info about you and the only way to stop that is to not use the web at all. Most of this is ad targeting for maximizing profit, but the police use it, the gov uses it, and I'm sure it's profiled for high level folks of interest so be smart with what you do and say on the Internet like you would in public if you worry about such things.

By the way, Rashomon is one of my favorite movies, not Ace Ventura. Toshirô Mifune rocks!
