You can block gift cards in most payment gateways, I imagine you could do similar with Apple's system.

There also is mixed evidence that Eli Lilly's stock actually went down from the tweet, given it reacted hours after the tweet and never recovered (usually fake news items effecting price will immediately correct back to the previous trading level.)

Several articles I read about it bury this deep in the article, basically alluding to "we'll never actually know why the stock went down." I would imagine their new Alzheimer's drug looming had more to do with it, but idk. It also becomes slightly questionable about if a quant, etc fund would not know the difference between accounts, when you really think about it...it sounds improbable.

What GP means is to go to a grocery store and lay out 10 American Dollars for an Apple-branded services gift card (what used to be called an iTunes Gift Card). One of these: https://www.apple.com/shop/gift-cards

You apply it to the brand new Apple ID you've made and use those virtual funds to make the in-app purchase in the Twitter app that, at the time, was the method of paying for Twitter Blue. (The purchase page even said/says, "You can only subscribe on the Twitter iOS app (for now).")

No blocking of prepaid or gift cards here; you're doing exactly what Apple wants and it's not Apple's problem that Twitter takes IAPs for a "verified" service.

If you're accepting payments for in-app purchases through iOS, all the billing for that happens through Apple. The app developer has no control (or knowledge) of how those payments were funded.
