well actually Ubuntu bundled spyware

https://www.fsf.org/blogs/rms/ubuntu-spyware-what-to-do

    Ubuntu uses the information about searches
    to show the user ads to buy various things
    from Amazon. Amazon commits many wrongs
    (see http://stallman.org/amazon.html); by
    promoting Amazon, Canonical contributes to
    them. However, the ads are not the core of
    the problem. The main issue is the spying.
    Canonical says it does not tell Amazon who
    searched for what. However, it is just as 
    bad for Canonical to collect your personal 
    information as it would have been for Amazon 
    to collect it.
