I see why people think this, but it is also anti-social. Once you've introduced art to the public market, two things happen:

- people form a relationship with and an emotional response to the art

- they give you money for the art

Now, the latter gets into questions like Sony or Steam removing games or films which people have previously purchased. A consumer rights question. People tend to feel they have been treated like a sucker when the publisher does this.

The former you are effectively rescinding the emotional relationship with the art. A much more complicated question. This can certainly be pathological - see kpop and the idol industry. But I don't think it's unfair to say that insisting that the art relationship should be totally unilateral and you owe the audience nothing, is going to anger the audience.
