Why only pay via PayPal or credit card

Why only pay via PayPal or credit card

I want to purchase a subscription but now I see that you can only pay with a credit card or via paypal and I don't have any of them, why not IDEAL.
How can I take out a subscription now?
I hear a lot of people complain about this and they then go to the competitor where you can pay with IDEAL.
