For someone that isn't aware of the existence of blockonomics, he/she is likely to get into BitPay. From what I have noticed, it's popular than the other service that has been mentioned.
I'm pretty sure Jon is responding to the starseeker's posts. Also, it doesn't make sense when you paid attention to it, since you'd absolutely need to know both before moving from one to the other.
Alternatively, did you end up writing your own solution, if so, why?
Unless there is no payment providers that can solve your problem, I doubt business would go that far. Time is money for them, and hiring someone to develop their own payment is a waste of money when there are open source solution available out there. Unless they don't really want to take control of the setup and fine with depending on others.
