Just because you expect someone to owe something to you, doesn't mean they think they owe you that thing.
If someone gives away something free, they can and sometimes do wash their hands of it. That doesn't prevent you from expressing your opinion on what you think they should change about the work, but they're not under any obligation to do anything about it.
Someone made a thing available. You can take it as it is, you can make noise about what you don't like, you can make it better, or you can ignore it and move on.
If someone is providing a mix of useful and garbage information, well, take your pick from the above.
