Well, the thing is that it wasn't so much about issues where it is a matter of opinion, like color or which particular source looks better, but issues that are indisputable imperfections which I'm unable to fix but most people won't notice them until they are told about them. And then you get into a situation, where I can't fix it anyway, so the criticism didn't have any positive effect on the project, but it did have a negative effect on the viewing experience of dozens of people.
But g-force's arguments convinced me that that isn't a sound enough reason to censor what people discuss in this thread.
