No one is "replying obliquely", I don't think. Generally when I post about this, there's a profusion of indignant outrage (usually about how I should use their magic ritual to propitiate the dishwasher), and one or two people also willing to spend the karma points to say that tracks with their experience.

I'm willing to believe commercial-grade dishwashers are actually effective, because only very occasionally do restaurants give me dirty dishes or cutlery. In personal homes, however, I've only encountered totems and superstition, but unlike internet commenters they don't usually get super outraged.

Maybe you are just wrong and basing your opinion on old, obsolete data? Granted I haven’t had to do any ritual of any kind using dishwashers for the last 20 years… but yeah. It’s not like I’m the one pointlessly wasting time hand washing dishes.
