If you use Instagram and your friends join Flickr instead, you'll have to move to Flickr or you'll lose contact with your friends.

If you use Pixelfed and your friends join Anfora... that's fine, because you can still follow each other as these platforms federate together through ActivityPub.

If any part of the ActivityPub network grows, all the platforms on the network get a bigger audience and all members get more potential friends.
