I don't know how many times in the post they say some variation of "it's your stuff, do whatever you want", but it's certainly more than once. While they didn't explicitly say it (again) in this particular sentence, "do what you want" is repeated enough times throughout the page that it's pretty clear that nothing on this page is a "demand".

"You provide an amazing service and I want to help. But part of helping is I need to understand what is it that you would like me to do."

Is a pretty reasonable take. I don't know how that translates to "really hard to work with", but, in their own words: "It's your project, you are welcome to do with it whatever you want".
