Tails is a portable operating system that protects your privacy and helps you avoid censorship.
So I tested it in a virtual machine and figured out that the default search engine is Duckduckgo which is not trade-free (https://www.trade-free.org/directory/rejected/duckduckgo/). I also found an application called “Electrum Bitcoin Wallet”. Bitcoin is just another currency in the game of trade as explained the “the origin of most problems” book (https://www.tromsite.com/books/#dflip-df_6562/1) and solves none of our problems.
The fact that EFF, the Tor Project and Edward Snowden recommend that operating system is a strong indicator that it avoids any form of data trade + fact that it’s free software, so I can download it, install it and use it give me the impression it is void of any other forms of trade. Therefore I give 5/5 blocks. The website also has no ads or trackers – nice!
