Unfortunately some people want to have some semblance of social life and in some circles dropping Instagram means decimating your pool.
Rather: dropping Instagram means improving the (average) quality of the people in your pool. :-)
This is the social equivalent of just throwing your hands up and saying “it can’t be helped”.
I cannot stress this enough: it _is not_ true. Deleting your IG will not cause your friends to stop being your friends.
Being on these platforms legitimizes their use. It makes the situation _worse_. It is a vote for surveillance and censorship of your most intimate personal connections.
