That's true, but that could be just his choice of printer. I've got a prusa that has done 100 km of filament (ok, it is the oldest one) and 50 bambus, the bambus are insanely reliable.

Agreed that stuff shouldn't be breaking over that kind of runtime. But the article leaves out a lot of detail that would have helped identifying what is going wrong with the printers, but that's not the main reason this did not work, the main reason is a lack of business sense.
