I would personally add a small amount of slack for bad taste satire (we were all young idiots at some point), but basically agree. Any signs of the other points, and that slack is gone, however.
I was mostly curious if the OP was acting in bad faith, or a useful idiot that could be reasoned with.
The problem is there are 2 categories. Microwave safe just means it won’t explode, or throw sparks. The other type sorely lacks a name still. It’s the stuff that is transparent to microwaves and so won’t heat up at all, except for heat transfer from the food.
