The only thing I get from this post is that Braintree delayed their payments due to whatever reason(without telling them why?).
All I got form that was "we cloned Uber, then didn't do due process when selecting a payment gateway".
Yes, the only reason this app exists is because Uber isn't allowed to run in Serbia.
Which isn't exactly germane to the issue at hand. Cloning someone else's business idea has no bearing on 'should they be able to earn money for services provided?'.
