I think they're referring to the idea of companies jealously guarding access to any and all source code because copyright doesn't protect them anymore, while FOSS authors have no protections.

I don't think that that's a realistic fear, though; this is basically already how it works with FOSS code being used in remotely-hosted SaaS systems and there being no effective legal recourse for FOSS authors.

It just doesn't officially say it yet in a law.
