You are right but then the project authors don't owe you support and don't want to support you if you are in that situation, so fork it or find another project.
And they have the right to refuse. Do you know how many times my PRs have been turned down after I already finished the work? Sometimes they only accept PRs if you're in their click lol. That's all fine but clicking on a star is so despicable right? What a joke.
