There's no need to presume lobbying. Freely released models, by definition, don't have a regulation body. It would be like replicators suddenly made it possible for anyone to produce automobiles or firearms with nearly zero variable costs. These things have life-changing consequences, so there are expectations of quality, safety and record keeping.
The simple truth is that our information tools have become so complex that they're capable of significant consequences. Bots already are being used to wage war on information, notably Russia's socio-political war that the U.S. doesn't even realize that it is in. That said, it doesn't mean that models must be proprietary. If anything, this must be treated like crypto protocols: open to many eyes and liberal amounts of sunshine to prevent anyone from encoding a Manchurian candidate.
