I can see if someone got it cross threaded and then tried to force it in they could possibly strip the threads. I've never had a problem with mine, and it threads very easily as they are pretty coarse threads. I would definitely not call it a "recipe for failure". Would you rather the dipstick be threaded with hardened steel, so that when you force it in cross threaded it stripped the aluminum threads of the generator? That's a recipe for failure, and I would much rather have the plastic threads of the dipstick fail. I'm sure it's a cheap replacement part. The good news is had the generator run dry, it would have shut down due to low oil pressure.
