No matter how much "free" software you will still be tracked. The government has access to all the data you use on their internet via service providers as well as the internet hubs.

Besides the government the data that the companies collect is used to improve their software, so is that really bad? I agree I do not like being snooped on, but the government is the only body I really have any interest in because it is in the constitution not to snoop on me without cause, the company (usually) doesn't provide such assurances/promises.
