Well I think it's one thing to walk away from the beginning and another thing entirely to walk away when the relationship online is already established. I think at least that's what Meta is thinking.
In my case, I left Facebook shortly after they opened it up from just colleges only and they made their first round of changes in the privacy policy. So I've kept those relationships offline already. Twitter I joined a week before throttling happened so leaving was lower risk

I also assumed that I was the exception to the rule and went strictly mastodon where I assumed most people use multiple social media sites.
I think the more solidified those relationships are, the more likely someone is to leave. Even so, the flip side of that question is, isn't interacting with / joining threads pretty much running back to them anyway, if not in a slightly milder sense?
