Part of the problem is that sarcasm relies heavily on shared group values (common wisdom), to make it clear that a given statement is meant in the opposite sense.

The icing on top is the tech-contrarianism that rejects common wisdom in favor of looking for an edge. It was innovative when done from the bottom up in a subculture, but it lands somewhere between tedious and horrific now that tech has taken over mainstream society.
