As I understand it, its not about the skill of the programmer, its about what can be arranged through paypal; being unstable and unsuitable for their needs (primarily subscriptions over one time payments.) This is sort of like complaining about the lack of Roll20 on IE (without chrome frame), when its IE that doesn't support html5. This quote from Nolan ( of the dev team) seems to cover the position fairly clearly. " It's not setup for subscriptions (programming it for recurring transactions is not at all stable), its customer service is dreadful, and it gives us very little ability to automatically track what's going on . What we're selling at Roll20 is software as a service... and you expect it to be running in the future, right? Which means we need to be able to plan and to track in-house; how many of what sorts of subscriptions are active, bringing in what sort of income? PayPal is AWFUL to deal with, and we are NOT alone in this opinion. Businesses as large as Blizzard still have a great deal of restrictions on their PayPal use, particularly internationally. We have no desire to have our small team spend our time chasing these problems." Emphasis mine, also Im not a mod so dont take this as gospel.
