Richard Stallman calls Ubuntu “spyware” because it tracks searches
Reading what he is talking about, Stallman's description is absolutely correct. If I am doing a desktop search for local files, it is not be expectation that that search will be transmitted to servers without my consent, and that it does so makes it spyware even if we don't also take into consideration that it is being done to track my interests for monetary gain in the form of referral links. Good on him for calling attention to this functionality.
