That is fair. I've only seen Stripe from the outside, and haven't even actually implemented it on any projects. Certainly I can appreciate how frustrating and disappointing it is to have some established player in the greater ecosystem come in and build a nearly direct copy of your service. I'm also sure that there's much more to Stripe, and payments in general, than the API and docs, and it's highly unlikely they can come up with a copy of the rest of the company.
