Corporations and trusts that are applying for supressors are having the Form 4 returned with instructions that it now must now only be held for "research and dvelopment" purposes. Evidently, the traditional purposes are no longer valid reasons for possession under new internal review regs within the BATF.
This sounds like ATF enforcing a state or local law on a trust, just as they normally would for a personal transfer. IIRC, one or more states (NC perhaps?) require certain title II firearms to state "R&D" as their use.
I doubt that's happening nationwide, or I'd have seen a great uproar on the NFA sections of various weapons sites.
