Jesus Christ man 😂 you’re looking for a moral angle but there is no moral angle here. A business has the right to design their transactions however they want, even if that design explicitly excludes people like you.
Some people are easy-going, they are more prone to trust, they want to test a product they don’t write an essay about it about it they just put their CC info in, try the thing, and cancel the sub if it’s not for them. If they forget to cancel i refund their money cause i need a happy customer more than i need 20 bucks. You don’t need to call them rubes just because they’re invited to the party and you’re not.
