This is why it's hard to build a profitable payment processing business.
In 2022: processed €767.5B. Net revenue €1.3B. EBITDA of €728.3M. EBIDTA margin of 55% - similar to that of eg Visa or MasterCard.
The difference? Cost basis.
Adyen employs about half the people as Stripe, mostly in Europe (their HQ is in Amsterdam). It’s not just fewer people, but, most likely, lower cost per employee (European HQ vs US HQ, and the wage difference between the two).
They offer lower rates, collect less net revenue, and have a far bigger profit than Stripe.

Our rates were also significantly better with Stripe in the US, though we were doing into the billions in annual transactions, which likely has a lot to do with it (we wouldn't have moved all of those billions to Adyen right away).
Which is all to say, much of what you say is true, but it's not like Adyen is a clear winner.
Taking on enough liability to wipe out the entire company in just a few days in the worst case scenario just to make a fraction of a cent of profits.
