I suspect much of the excitement over Threads is

A. Bots & farms, come on we all know how this works

B. Some big names were paid to migrate on day one (not mad about it, why wouldn’t they)

C. Huge heaps of schadenfreude because Elon has been such a horrific shit everyone wants to see him cry

It may stick after all those have subsided…but it’s still Facebook in the end. They don’t need more opportunities to curdle brains
