That is where you are wrong. KBLB has a fiber. The others do not. They think they have an idea that might be able to be scaled up when the technology catches up.
But there is only one commercially feasible spider silk.
KBLB is the one that has it.

If you can show me anyone who can produce ANY spidersilk protein fiber at the same cost as normal silk please do so.

KBLBs silk can be made for the same price as normal silk.
