You’re not wrong, but consider that people who justified sticking around for some reason or another might leave because the brand change (to a name that is so brain dead even a little offensive) finally hits home for them that it isn’t going to be the same.

A brand name change is about the single most overt thing you can do to send the message that a product isn’t going to be the same. And when that happens, people tend to look at the recent trends for that product to get an idea of what to expect. The recent trends for Twitter happen to be right-wing echo chamber.

So yeah, the people who were going to leave have largely already left. But this brand change is going to be effective at galvanizing those who remain.
