Read the book “Irresistable: The Rise of Addictive Technology” and I suspect you’ll have a different opinion. People get addicted to everything that exists and you’re essentially blaming the victim. The difference is also that Facebook designs its Newsfeed/Instagram like a slot-machine that encourages people to just keep hitting refresh. Maybe they’ll see something new or they’ll get a like...
Also, most people aren’t nearly as smart as the people on this thread. So you have fairly average folks getting hooked on tech that was designed to be that way by psychology majors and data scientists.
Also, Facebook could do a lot better in removing propaganda and obvious lies. They just don’t want to remove all the hundreds of millions of fake accounts they report as real to their ad buyers.
