Somehow I'm not a fan of HN using this community for lobbyism purposes.
It's expressly the intention of democracies to hear from constituents (and conversely: groups of constituents). That we happen to call that feedback loop "lobbying", and that the term carries some societal baggage from corporations using/abusing it is unfortunate, but shouldn't be an indictment of what is otherwise a democratic function.
Some group FOO with a shared ill should be able to convene about it and petition congress about it.
