I don’t think it’s quite like that. Border seem aware of the IP issues. They clearly state they don’t have the CAD work, only the physical moulds. It’s a ricky question whether production from the moulds in effect recreates or uses the IP. I suspect that’s why Border say they have modified the moulds and corrected errors.
What seems absurd is Wingnuts now spending what must be large sums on lawyers rather than buying back the moulds in the first place. Wingnuts seemed quite happy to owe large sums to mouldmakers (if what Border says is true and that seems to fit with e.g. Meng) but now gets aggressive when those mouldmakers try and recoup their losses.
