You guys think that the franchise growing popularity and already established means that "the game did good". You think that Skyrim didn't do wonders for FO4's sales? You think that is the only factor in sales? There are many factors and the company strives to maximize each one.
The Witcher was a niche franchise to begin with and CDP a small studio. If any statistics get released you will see how things work.
Got to laugh at the pre-school level argument "haters gonna hate". There are no special flowers or hate involved. It's consumers and products. Simple as that.
You perceive things only from a certain viewpoint because you can only see that much.
For example when a plain bad game is released, are the consumers criticizing it, "special flowers" or "refined taste haters"? No, they aren't. It's only your emotional attachment in this case that allows you to see things like that. Was everything at their peak of their popularity criticized and "condemned" by the masses? No. It's just your narrow viewpoint that makes you believe so.
