Think economics and not technical. Since there were very few returns because of reverse polarity, it isn¹t cost effective to add the protection to each board. For example, circuitco has shipped 177,000 BBB multiplied by $10 protection is $1,770,000. Less than 20 returned because of reverse polarity at $55 each is $1,100. The solution is obvious. Gerald is very smart and he knows what he is doing ;-) Users just need to be more careful.
