By this logic, you want a complete monopoly of a single platform? Because that’s the only possible way to have “no barrier”. Unless GitHub starts federating with some kind of standardized protocol. This is a huge technological and monetary barrier for GitHub, which is why it will never happen on its own, so if users are not willing to try platform-independent workflows then the problem is frankly not the competing platforms.
Have to agree, it’s a funny story but charging someone a stupidity rate for nonexistent work isn’t justified by that person being stupid and a pain in your ass. Unless your circumstances force you, you can always just refuse work from customers like this. So many people downvoting this is disappointing.
