Sure you can. They are not trying to make the point that no food is edible, they are trying to make a point that depending on who you ask, you will end up hearing that any and every type of food is inedible.

I get what they are saying. If you read the comment threads here on interview experiences, you're going to encounter groups that dislike or want to forbid every kind of technical screening technique. It's easy to read comments here and come away thinking nothing is OK and everything is unfair.

That’s not the point they are are making at all. They further expanded on this by talking about the straw man hacker news user who doesn’t think they should have to do anything to get hired.

It's the exact point they are making. The union of all dislikes and eloquently put putdowns is exactly what many of us bring with us in our heads every day.

But you can ignore anyone that says "this food is not ok to eat because I once tried it at a bad restaurant and I didn't like it".
