As I just mentioned, I think the board of directors, whether they are paid or unpaid, should actually be considered in-house lobbyists.
One that maybe wasn't mentioned and that I didn't put forward, but that I've heard during different discussions, is how to avoid certain situations, such as designated public office holders coming to speak to government lobbying, whether they're paid or unpaid. Rather than changing the definition of paid to include unpaid, I think one consideration might be to expand the definition of designated public office holders to include that you cannot lobby for whatever period—right now it's five years—whether you are paid or unpaid.
