It was a huge matter of invasion of the PC... most were uncomfortable with the thought of someone snooping about their PC...
However some believe we allow basically a spy device to "track" their day to day information... Alexa, Cortana, Seri, Whatever you want to call it... it is what it is... What do you suppose Amazon, Microsoft, Apple and all them do with those devices??? You think they gather data? Monitor it??? Spy with it??? Never know do you... Just thinking about it. So many things we take for granted... and hackers are everywhere... what do you suppose would happen if they hacked those devices??? Nothing is "safe"... and nothing is free from being hacked.
Think of shows like iRobot and such... and you wonder how far are we from a world where they monitor your every move... Minority Report... If you went back 100 years or 200 years... and explained what you could do today... what do you think those folk would think of how we live today???
Punkbuster was a nice dream when it was brought up but to think it was the "end all" of cheating is fooling yourself.
