That is more about sponsorship disclosures. A better parallel would be with disclosure of paid or sponsored material on broadcasts.

But yes, I’d be all for that. If a bill is drafted, all the entities that had input into that draft should be listed. If a politician gives a speech at the request of a compensating entity, that should be disclosed at the beginning: “This speech was paid for in part by Audible. More on them at the end of the speech”

It’s more like publishing who actually wrote legislation. Often it’s lobbyists who write laws and politicians put their names on them.
