There are many, MANY low-income owners who would certainly want a "flawed Brompton clone" which does not have quality parts, but is super-compact and runs well enough. They don't care if 15 months down the road, it has a rusted handlebar and develops a hairline crack on the body. As long as it gets them from Point A to Point B, it's all good.
You seem to lack the imagination to understand that a "cheap Brompton clone" which has the prime advantage of a Brompton - minuscule fold - is good enough for the vast majority of transport-based bike riders. They can easily carry their bikes onto a crowded bus/train to the factory instead of leaving it chained to a lamppost. Someone is bound to realize that sooner or later.
That said, I reiterate that I respect Bromptons and their pricing. They have done a great job keeping jobs in the UK while others are leaving in droves. That definitely comes at a cost.
