Considering just how important social media has been in the last few years, I don't see how suggesting people should quit social media is silly. The US has had a president who largely communicated with his constituents through Twitter (one-way as that communication may have been), celebrities get their careers re-ignited because Twitter rallies behind them, influencers are... a thing?, social media management is a full-on career for people!
At this stage, the world is actually quite stuck with social media and, honestly, I can really believe that something as seemingly minor as quitting Twitter can change someone's demeanor, quality of life and so on. Social media is a bloody juggernaut, sometimes it's best to move out of the way.
