I mean, I would hope GitHub isn't using Stripe at their scale, but I could also easily see this happening (them negotiating great rates from Stripe, I mean) at their scale and, particularly, their level of prestige and since it will be used by developers. For anyone else, though: please note that PayPal is cheaper than Stripe, with bulk rates that kick in sooner and support for a special micropayments tier on smaller tickets (though this option isn't quite as good as it used to be; I'm grandfathered in ;P). Stripe frankly gets away with a lot on price simply due to being the "darling" of developers, who don't necessarily check and often refuse to negotiate no matter the cost to their bottom line (see how expensive people assume Akamai is ;P). I was shocked how much Stripe wanted to charge for AliPay, as an example, as if you work with AliPay Global directly (instead of going through Stripe) the cost is 3% with no flat fee, while Stripe decided to keep their $0.30 "I don't know what I am doing I just want it to work" fee.
