People must be allowed to judge and write off artists solely based on the last thing they made

People are reading this text in two ways:

1) A suggestion is made for the readers and to the society to change how the judge and think about artists.

2) Writers tries to convey new norms, forbid judgement.

What do you think the writer tried to do here?

It is preferable to take a more nuanced approach to judging artists, looking at their entire career and recognizing the inherent subjectivity of artistic appreciation, but people have a perfect right to judge an artist on a work of art, it simply shows a certain closed-mindedness

At the same time, artists of every kind have to contend with the fact that this is currently a golden age for art. We are confronted with more art of every kind than we could ever consume. The cost for moving on has never been lower.

So while an artist should be allowed to have down periods, it also shouldn't be surprising if people move on. We're not looking for needles in haystacks anymore, we're looking for needles in a stack of needles. There may be value in coveting needles and hay from a particular artist, but that's an intensely personal decision to make.
