There are actually a lot of kosher "bacon" potato chip flavors. The flavor is usually faked with smoked paprika. "Bacon salt" is also kosher, for the same reason.
In that case, keeping it kosher widens the market a bit, and the man on the street probably can't tell the difference anyway. Beside that, it's probably cheaper and easier to flavor with smoked paprika than actual bacon.
I have some truffle oil at home and always wondered how it could possibly be profitable to produce; one wouldn't want to squeeze anything out of a truffle. I guess now I have the answer, but I'm not too upset about it. It's probably as close to truffle-flavor as any grocery store in my state will actually get.
