That’s probably the case, or at least a part of it, but it’s crazy that it’s gotten to that point. If somebody finds a food item in the wild and decides to eat it, the consequences should be 100% on them. It doesn’t even have to apply to food, either.

If I find a block heater on the ground, install it into my car, and then my car catches fire; I’m not going to go after the manufacturer of the block heater. I’m the idiot who decided to do something stupid.

That being said there’s real life cases which indicate that yes, people are stupid and will sue over their own stupidity, so I’m not surprised at all.
