> Using the word "addict" is a cop out to take away personal responsibility.

It's not a cop out. It's a fact. Social media can fit the exact definition of "addiction" for some people. Personal responsibility is present if you're abusing a drug or social media.

From your comments, it appears you aren't affected. Great. Similar to how you probably can't relate to a heroin addict means you can't relate to a social media addict.
