There is an argument to be made here against the statement "People are not entitled to anything entertainment related. Don't like it? Move on"
And that is, this should not be the statement to handwave this petition away or the discourse away, because it set a dangerous rule for yourself. Using a hyperbole, for example, if there was a popular media, take 'Blade', but they made the mc a white dude, with black face. The movie was released in theatres, made alot of profit due to the racist audience it has bought in. Now the general black audience signed a petition to have the movie from being shown anymore, banned, because it offends them. Using your statement, they are not entitled to anything entertainment related and if they don't like it. They should simply move on.
Now if you don't like this petition or people who signed the petition, you are not entitled their opinion or the criticism they have or the demand they have and if you don't like what they are doing, you should move on. Do you see how it can be thrown your way?
And I just wanted to show that the statement is dealing in absolute. Anytime absolute is used against human nature, it sets a dangerous precedent.
Now, did DnD ruined GoT last season, it is all subjective. Did they handle rape subject matter of Sansa appropriately, not at all. But handwaving these concerns or questions with don't like it, you are not entitled to it, and you should move on, is not the ideal way to approach anything media related.
