It occurred to me how easily this headline from Casey Newton’s excellent Platformer newsletter could be written about academics instead:

The reasons are slightly different but this passage about inertia struck a chord:
The first and most obvious reason is inertia. Journalists spent more than a decade building up their presences on Twitter, and they were never going to abandon the site collectively overnight. As long as they can still drive traffic to their stories, discuss those stories in public with their peers, and grow their audiences, they have little reason to leave. Some, like Big Technology’s Alex Kantrowitz, even see opportunity amid the decline: if big publishers won’t pay for Twitter Blue and the potentially bigger audience that comes with it, he will — and, he reasons, his own work will stand out more.
