It is difficult to find information on these companies regarding their motives for discontinuing their research into creating Spider Silk.
I admit that I have not put a lot of energy looking into them, but I have been able to find a few patents:

DuPont:
https://www.google.com/patents/EP1712561A1?cl=en
https://www.google.com/patents/WO2001090389A2?cl=en
https://www.google.com/patents/US6268169

It looks like DuPont attempted to produce it using silkworms, plants, and E.coli.

BASF:
https://www.google.com/patents/WO2012025582A2?cl=en
https://www.google.com/patents/WO2008155304A1?cl=en
https://www.google.com/patents/WO2007082923A2?el=en

It looks like BASF was woking with other producers of the proteins and not producing them themselves. They specifically mention in one of their earlier patents the use of transgenic goats. Another more recent patent lists Thomas Scheibel and Daniel Huemmerich, lead scientists at AMSilk, as inventors. I would not be suprised if they were working fairly closely with AMSilk and still playing with their proteins. Unfortunately, they are a German company and I don't know German, so there may be information on them that I have yet to discover.
