It is what it is. I'm not holding a guns to anyone's head, nor telling them what they should do, or not do. If these products don't interest you, you could just as easily hit the back button from the get go. Instead you choose to post repeatedly how this isn't required, and how in your world all one needs to do is offer clean water. To me, that is sticking ones head in the sand. If you find that terminology offensive, oh well.
