Funny you should say that mobile users on Reddit have no UX problem with vertical videos. Here is how the above link looks like on my mobile device. Original link (to classic reddit UI), mobile version horizontal, mobile version portrait, respectively: https://imgur.com/a/JU4v3rn

The video has a full screen button which can be seen in your screenshots. Tap it and the video fills the screen in portrait mode on both the old reddit and the new mobile reddit, at least on my Android device.

I find it terrible "progress" that one has to press a button to get a functional view.
