I'll bet a buffalo nickel that this is so Musk can guarantee eyeballs on ads.

Arg: expected eyeballs on ads not 100% because blocking. This shiny new 'X' will guarantee 100%.

Tinfoil: If he can disrupt B2B on ads and seize more marketing market share, he looks like a genius and gets to add a payment feature to X. I don't think he's very creative and will just remake PayPal with a fuckton of extra steps.
