This question already has an answer here:
- Ubuntu with spyware? 2 answers
- It does not meet all four freedoms of free software.
- Canonical encourages the use of non-free software
- Ubuntu is spyware as e.g. the dash search queries are also sent to Canonical and Amazon to include further online results and ads!
They say that since 12.04 the local dash search automatically also performs an online search at Amazon. The feature might be turned off in the System Settings and all queries are anonymized by Canonical and routed through their servers, but that means that at least they know what we search. (Reference)
Additional to these accusations, I've also heard that e.g. the automatic bug reports may include more personal data than needed.
May please someone with deep knowledge of the mentioned parts of Ubuntu, it's security and privacy options and/or Canonical's policy on this comment on those statements and verify them? How much is true, what is wrong or exaggerated, how can the normal user avoid being spied on by either Canonical or any third-party companies like Amazon? Do the latest versions of Ubuntu still have the automatic network search and other critical features enabled by default or did/will they improve this recently/soon?
Thank you for confirming my trust in Ubuntu or opening my eyes about it - whatever is necessary.
Note: Please don't just write something you've read anywhere if you're not sure. An answer based on prejudices or what's believed by "normal"/non-expert users are not very helpful in this case.
