@Gargron Mastodon has a built in user base of 0 basically so that’s a total gain of 1.6M, Instagram has a built-in user base of like 800M, so Threads has 730 Million people who aren’t on it yet. So if you think about it one way, more people will choose not to use Threads than will choose to join Mastodon.
If my math checks out that’s a good thing.
