Purposes forbidden include all crypto and crypto related purposes, regardless of claims as to green-ness or ecofriendlitude, which are definitionally lies. Later inclusion or association with purposes that willfully harm the earth will revoke and retroactively invalidate this license. If now or in the future you, separately from your uses and derivations of TTHfPG, become involved with willfully harming the earth, the license fee increases from free to 100USD, or 100EUR, whichever is greater at the time.
