I think the battle is lost, but I'm a little bit sad seeing the sky over a city being filmed in vertical video.
Youtube doesn't post process vertical videos correctly, while Facebook, Reddit, Instagram, and many other sites keep the processed video in its flexible aspect ratio - primarily for their mobile users who would have no UX problem.
Interesting how that hasn't made it into the discussion, I feel like people will just stop talking about it when the UX is fixed
As good as it was, I never wanted to watch videos in that way.
