You are right about the big shiny button. So perhaps there is another big shiny button right besides it that says: "Delete all H.264 videos right now" so only the VP8 copy is left. Think about it: Chrome can read it, Firefox can read it, Android can read it. Perhaps iOS or IE<=8 cannot access YouTube anymore? Tough luck.
It is a bit thermonuclear: as a threat it looks great, in real life it sucks.
