Nothing strange about it. You can always have an opinion, but opinion are like assholes. Everyone has them, and just because you have one does not mean everyone should see it. A perfect example of this is going to a page from an NTR artist, and then blasting and shaming everyone who likes NTR because it is immoral. Or going to an interracial artist page and complaining cause their is a black person out of it. In this context people wanting to share their negative opinions about things ESPECIALLY when they are a free rider makes you look ungrateful. Not only that some of those negative opinions were not just complains about quality, but trying to rush an artist on a project that THEY ARE NOT SUPPORTING. So now you are just an asshole. There are plenty of ways to be critical and not be a jerk. It as always depends on context and execution.
