This is getting down voted, but it's true.

I've ditched those forms of social media, and haven't really had trouble keeping in touch with most people I'd like to keep in touch with, whether it's emails, calls, texts or regular meets/activities in meatspace. The people in your life who truly care about you will make a genuine effort to remain in touch with you.

If people don't want to make that effort, why do I need to be connected to what they're doing every day?

But you all already have Instagram. If someone wants everyone else to sacrifice to suit them, that sounds like a selfish person and a selfish friend.

I don't believe the willingness to install yet-another-messaging-app is a good measure of friendship value.

Between SMS, messenger, instagram, whatsapp, discord, slack, ms teams, signal, there's a point where juggling too much messaging apps become a burden instead of convenience.
