This is absurd and borderline offensive. Much like the "green" multi-use shampoo bottles (which are plastic and are thrown away when they are empty, so are not really environmentally friendly), this is not environmentally friendly either - it's clearly just a revenue generation scheme. Many people would just end up throwing the bottle away since most people do not leave room in their carry-on bags for a water bottle souvenir. Hopefully, they still have wrapped plastic cups available so you don't have to drink out of the reusable coffee mugs / water mugs that are cleaned with the same rags used to clean the bathrooms. Yuck.
