In a way they're doing it better. Twitter only seems to support MP4 whereas gfycat et al will deliver WEBM or MP4 based on the user's browser.
Agreed. MP4 doesn't work on Firefox (out of the box).

Just a nitpick, JPEG always encodes the color channels at half resolution. It's amazing how difficult it is to notice this, though.
No, there are 4:4:4 and 4:2:2 modes in JPEG. H.264 also defines such modes, but no consumer hardware decoders support them so they aren't commonly used.
This article makes it sound like Twitter invented a whole new optimization, when they really just recycled a concept already in use by gfycat ( http://www.gfycat.com/ ) and MediaCrush ( https://mediacru.sh/ ).
This is on a fully-patched RHEL6 workstation: http://i.imgur.com/NleqJTD.png Another example of "use bleeding-edge tech or go fuck yourself" from the modern web.
I suspect some implementation issues rather than a GFY attitude, it doesn't work on FF or Chrome on OSX 10.9. Safari works though.
The upside is that users get a reliable experience. the downside is that laptop Chrome users get a reliably lower battery life, as VP8 isn't typically hardware accelerated.

You should probably qualify that somehow, because MP4 works for me on Firefox (on OSX 10.9).

if you want to try to do this yourself, our code is a good reference.

Support for mp4 isn't bleeding-edge tech on other operating systems / distributions, unfortunately. It's a couple of years old in terms of being supported by Chrome; it's supported in Firefox as of last August. At this point, desktop configurations that can't play mp4s are at risk of being considered "broken."
Is it really that difficult to supply a free format like WebM in addition to patent-encumbered H.264? If you only supply H.264, you're cutting out Firefox on OS X, Chromium, and Opera.
I'm with you in spirit, but in practice I think we can all understand why people often just go for H.264
