Thank you! I had the exact same reaction when a coworker told me about this. There are millions of people who would take your old phone off your hands.
If you actually watch the video, it isn't exactly encouraging you to smash your phone, it is just using it as a metaphor to move on to new technology. I'm sure they would love you to donate your old phone to one of these charitable organizations.
And if you look at the form, it has a field "Destruction method", for which the example text is "Hammer / Baseball bat / Screwdriver / Fire / Blender / etc."
