Recovering from World of Warcraft addiction at age 12 (having spent the time fully immersed all day every day) caused me to read B.F. Skinner's research.
I was quite shocked reading about the Skinner boxes and felt empathy for the mice after having been trapped in one myself.
By coincidence I went with a friend to a lecture at the local university at this time... some guy called Richard Stallman was speaking about computers.
I came home and installed Linux, I have been learning what I need to participate in this fight ever since.
Originally I just wanted to be free from manipulation, so I put in the hours to protect myself.. but now I want everyone to be free from manipulations so I try to find out which kind of software I should contribute and maintain to move us closer to that dream.
