I think the likelihood of a 3D printer catching fire is WAY overblown, and having done a little research, it seems that there have been, at most, two reported cases. However, these two stories keep getting posted over and over, making it seem like this is a huge problem. Therefore, like so many other things on the Internet, the meme takes off and acquires a life of its own.
I very much like this approach because it doesn't require making modifications to firmware, something that seems to screw up a lot of people's printers. I'm basing that last statement on the huge number of posts, just in this forum, which start "I upgraded my firmware so I could enable thermal runaway protection, and now my printer isn't working right ...".
And, BTW, if you read the most commonly cited story about a 3D printer catching fire, the person who reported the fire says it was most likely caused by the heating element in the hot end falling out. Thermal runaway protection would not have detected any overheating in that case.
