I couldn't say if there was any specific activity. I think in the examination of the rules related to the political activities of charities it was identified that the spirit of the law is that a charity is supposed to conduct its own charitable activities, and to the extent that it's involved in political activities, that those be limited to some small portion—10%—of its charitable activities.
Looking at the regime and saying that a charity could be funding the political activities of another qualified donee by giving it a gift is sort of outside of the spirit of the law, which is that they should be engaged in their own charitable activities, not funding the political activities of other charities. So that's sort of where an improvement to the rules that would apply to all charities suggests that if you're violating the spirit of the law, then here's a way it could be done.
