I think a large part of this is just users being complacent. As long as the platform doesn’t completely change, most users will typically just keep trudging along.

For example if you remember the whole WhatsApp controversy from a little while ago. Pretty much my entire extended family communicated solely through WhatsApp, and they all were promising change, moving to signal, deleting fb and so forth. When the time actually came, everyone made signal accounts, and a few really switched, but to this day everyone still uses WhatsApp.

I’d guess that as long as people’s “interests” are on the platform, they will continue to use it.
