It is only a downside for people who want to control and have power over other people - socialists, communists, fascists, dictators and any other authoritarian governments. For people who like freedom, this is a plus, although even more privacy would be nice.
Agreed. I wonder how they are going to track down the person that stole the coins from nicehash. We'll just wait and see I guess.
