It baffles me a bit that bike manufacturers keep moving incrementally towards the American pattern BB, which has always worked but which they somehow pretend doesn't exist. Why ignore a time-proven design that is free and open, to make a half-assed approximation of it that has problems?

You are expecting engineers to all have the same educations and the same historic knowledge. In fact most engineers believe themselves smarter than those who came before. We are seeing the same thing with the Millennial Generation wo think that older people are stupid and they are God's gift to the universe.
