I'm afraid that's now how opinions work. You certainly don't have to heed the opinions of people who no longer watch the show, but that certainly doesn't mean that what they have to say is, in any way, invalid.
So, some people asserted some claims you didn't like, so now anyone with opinions similar to those individuals should lose their ability to express dissatisfaction with a product they feel is not living up to the potential it once showed?
Oh, I see, so you're making these claims based on the actions of a single individual whose opinions you don't have to listen to or agree with.
