Well the number of people is a key difference. Take your primal, for instance. It's nowhere near Twitter in UX. And they will probably never be.

Even focusing all that money in the UX at the expense of everything else, like not integrating with virtually anything, relying on centralized caches and even KYC people to use their custodial wallet.
