You mean to get something like Ubuntu that does the same thing?
Let's set this straight: anything that gives you suggestions (for search, products, dictionary definitions, songs, etc) from the internet, is by definition sending your query to some internet server.
Next drama: Google searches send my search queries to Google.

He obviously means something not like Ubuntu (or at least Unity in particular) that does not do the same thing. There are many many distros meeting this requirement, it's disingenuous to try and imply everyone is doing it.
If you want to use OS X, you need to play by Apple's runes. If you want to use some kind of Unix-like system, you don't need to play by Canonical's rules. There's a myriad of Linux distribution, not only Ubuntu, and then there are the BSDs too.
I have been a faithful Apple user for years, but this single report causes me to seriously consider switching to Linux for good.
