Slipping out of a Philips head is not stripping it. If you actually look at the type of Allen bolts those people are talking about (one of the posted a picture of the hex bolts they used on one of their projects), yeah I can see their arguments holding weight. The bolts they're generally using have very thick heads and allow for more of the hex key to slide into the slots. For as shallow as both Allen and Philips slots are on hardware, is is definitely easier to deform the slots to the point where the bolt cannot be turned on Allen bolts. Even using the correctly sized key on hardware, the slightest slip does not push the hex key out of the bolt like a slip does with a Philips screwdriver. Instead, it just deforms the hexagon as the key turns within the bolt.
Oh look! Here's a quote from one of your own links that backs me up: "Once a hex bit slips either the screw or the wrench is done."
So yes, you are still an idiot.
