In defense of that mindset creating something for personal use often involves 5% or less of the effort it takes to bring something to market. Or as an EE friend once said about his home built hot-tub if X went wrong then scolding hot water would shoot out of the pipes but it's not something I am worried about because I would freak out and pull the plug if Y or Z started to happen. Which transforms a huge fundamental flaw in the design to something that's not that important.
