Probably wouldn't take legal advice from duion, he tends to have his own twisted definition of words that fit his anti-establishment views better.
personally I would generally argue that personal use only is an anti-commercial option, otherwise, there's a huge set of 'personal use only' software I can personally use to make money I suspect is a poor defence in court, and i wouldn't rely very much on a 'but duion said' defence either.

linked this, but a simple scanning of any other page with a stipulation of 'personal use only' and not even the higher bar of 'strictly personal use only'...
If you are really concerned, and potentially you should be because legal terms are legal terms, a simple email to the developer might just solve the problem since much of his stuff is freely available and some of it explicitly allows commercial use iirc
