Of course, if you live in the US, the stop killing games thing doesn't matter because you genuinely cannot do anything about it. The only reason the campaign has teeth is because Ubisoft is headquartered in France, and France has strong consumer protection laws where if a product stops working after a while, they have to clearly tell you that upon purchase. Of course, no gamer ever checked because who wants to call up a government authority. So this is all an unsettled legal gray area as it pertains to French law. Publishers however don't want to segment their product line so usually once a consumer right is upheld in one jurisdiction, everyone else gets it for free.
