I would find it hard to argue that any of the current POTUS work has been competent.
Pretty much any competency can be demonstrated that way.
The original comment was arguing whether any of the POTUS work was competent. And that H1B change seems to have been competent, according to the general consensus on HN.
Is the entirety of the rest of POTUS' work incompetent? Maybe. That wasn't the original claim though.
