> write code as simply as possible is tautology

What? That has nothing whatsoever to do with tautology. It's just a statement you agree with. If everyone else agreed with it, it might at most be a truism or an uninteresting statement, but evidently they do not. (They might claim to, but reality shows they optimise for other things - in my experience the simplest work, which does not always mean the simplest code, especially when you're accustomed to the mystic rituals of the Javanese tribes.)
