It's not billions. My assertion is they will throw away processing millions to ensure they can continue to process billions.

Paypal earned 30b revenue in 2025, without any specific numbers, it's a safe bet that high-risk merchants are at least several billion of that total.
replyHowever, even if it were only in the hundred millions, there's no reason to throw away millions of dollars. The reason PayPal services these lines of business in the first place is because they make money doing so (since unlike Stripe, PayPal's product isn't subject to the constraints of the card rails).
