Taiwan got expensive hydroforming tube bending machines in the later 2000's and it made the orange fabrication look a bit old fashioned, I also suspect their reluctance to move away from single pivot while everyone else perfecting linkage designs didn't help, it puts all of the quality in the system into the shock which needs to be perfectly setup to work nice (and expensive shock needed)
they were the best in early 2000's but by time I could afford one they were expensive and not as good as other things so just not worth it
feel bad for them though - whole bike industry in the loo right now
