Graham pointed me at Grey’s Law which is another form of Hanlon’s Razor.

First you take Hanlon’s Razor:

“Never attribute to malice that which can be adequately explained by stupidity.”

Then you modify it to take the form of Clark’s third law:

“Any sufficiently advanced technology is indistinguishable from magic.”

Which results in Grey’s Law:

“Any sufficiently advanced incompetence is indistinguishable from malice.”

Not shockingly, this came up in a conversation about phone companies.
