That is an old rule: Don't mistake malice for bungling.

That rule doesn't work in the modern age. The modern malicious clearly try to cloud there BS in incompetence.

It isn't necessary to emulate incompetence. Incompetence and bungling is the default state, and very hard to avoid.

Hanlon's handgun: don't attribute stupidity to what can be adequately explained with systemic incentives promoting malice. It applies here. Stupidity is extremely unlikely.
