In the world of ebooks and publishing "Special Snowflake" is a term with history.
It dates to the price fixing conspiracy trial where the judge was flooded with self-serving and legally dubious briefs ( one even in comic book form) arguing that antitrust did not apply to publisher collusion because their business was unique.
The judge, relying on extensive legal precedent...
(Good summary here, as a refresher:

...dismissed the briefs and their argument by using the term "special snowflake".
Since then, the term has ( in ebook circles) become shorthand for "misguided belief that the laws of economics/nature/the state do not apply to you".
In the broader world, "special snowflake" has taken on a deeper, more pejorative, decidely political, meaning referring to a very specific kind of self-centered cluelessness that devalues those around you.
In this year of 2017 you do not want to label anything you value as a special snowflake.
In fact, "special" by itself is becoming an ironic putdown akin to the southern "bless your heart".
Times change.
Language evolves.
