My interpretation of what happened here is that a legislator who opposed the bill inserted the names of the lobbyists as a joke against the bill, which has now paid off. The article says that the original list did not include the names, they were added during the legislative amendment process by a legislator.

While corporate authorship of bills is a concern, I don’t think this particular mishap is a direct result of that and in fact seems to have been an attempt to subtly criticize it.
