Because it's buggy as hell, and also because it's the product of the dev throwing a hissyfit over people liking "the funny" and removing it in a rushed update despite promising bigger, better and less frequent updates.

The spoiler wasn't even there when this first dropped. Calling people that just wanted the spooky signal bug fixed "special" and releasing a purposefully stripped back version is just mean spirited. Edit: I now realize it's not a "stripped back version" and everything returns to normality after enabling the funny setting. Still think this was unnecessary.
