Stripe provides value-added 'premium' service which competes with merchant banking solutions offered by most EU banks, and Stripe does not have a dominant position. But in general, yes, EU does place a LOT of attention to these deadweight transaction costs, and has had large interventions - for example, if you look at the price listed in this very article, the reason why 'international cards' have 3.25% fee and 'standard EU cards' have a 1.5% fee is primarily caused by EU-imposed changes to interchange fees which get paid by the acquiring/merchant institution (including Stripe) to the issuing bank.
