I used to think the same when people spoke of social media being addictive, but not any more. Drugs aren't autonomous either, however they clearly do remove some people's autonomy. I can well imagine now that a person could be addicted, particularly if he's grown up with it and has used it in the past to avoid facing his problems.

“Thus, a good man, though a slave, is free; but a wicked man, though a king, is a slave. For he serves, not one man alone, but what is worse, as many masters as he has vices.” ― Augustine of Hippo

(Not saying anybody around here is wicked just remembering a striking quote)
