I’m sad to see they found PayPal the best option, and that underscores how much work is needed in this space to provide competition. I’ve used PayPal for years and I’ve always found it to be the absolute worst, last ditch option for when nothing else is available. Their business practices are not customer friendly, their currency conversion and handling of that is a borderline scam, and the way they partner with eBay presents so many issues for people who use both services. I really hope something comes along to knock them off their perch in that particular space.

It seems like they're partially using PayPal because they're maxing out credit cards regularly (!?)

If my business was maxing out any sort of credit card I don't think I'd be donating 3% of my revenue to open source projects in the first place.

We're using PayPal for a couple of reasons (named in the article). But the reality of an early stage (bootstrapped) startup means you get a crazy low credit limit, so when we paid upfront for our server hosting that got us close to the limit. Besides, cashflow is very different than cash on hand.

Yeah, I've got the same general feelings about PayPal as well. I'm hoping that GitHub and Stripe both evolve their offerings in the future to be more honest and easier to use platforms.
