When it comes to social media, people rarely "exit" when they're very dissatisfied. A few people do, but most of the ones who are displeased with changes in the service respond by shifting some of their previous uses of it to other services while continuing to use it in different or more reduced ways.

For example, people mostly didn't leave Facebook after getting the message that Facebook is bad for privacy, but in the early days of Facebook I could find nearly every single one of my friends' phone numbers and home addresses on their profiles, and the "phone book" feature was very useful. Now, hardly anyone puts their address there, only a minority put their phone numbers there, and the "phone book" feature is mostly forgotten (I don't even know if they've removed it, I haven't looked for it in a couple of years at least). What kinds of photos people post, and how much they share, has changed a lot over the years, but most of the people who pulled back in this way didn't delete their accounts, and still post material there when they don't care much if it "leaks".

I've observed a similar thing with Google services over the past couple of years. People pull back by shifting some of their activity to other providers, while continuing to heavily use Google.
