Now its 600KB (100KB compressed) JSON + additional 8MB desktop_polymer.js (1MB compressed) that needs to be compiled/interpreted before anything starts showing on the page - its all dynamically generated Client side. 1MB js player is on top of that.
That said, either youtube-dl or Invidious [1] will do the trick. The latter can be self-hosted and emulates a more familiar YouTube experience (minus the tracking/recommendations).

How does that work when you’re out on your iPhone and just want to check a video-link someone sent you?
Oh wait. It doesn’t.
First, choose to go out with a more open platform (if only by a bit) that at least allows you the freedom to install apps which don't necessarily come with a corporate overseer's approval.
Then, install the Youtube Vanced app.
Shut up and take my money
Technically, I signed up for Google Play Music way back when it was initially launched, and have since been upgraded to YouTube Red/Premium and have kept it.
Unfortunately, in recent several weeks I started to see an occasional ad even in Brave. As for now, these ads are really rare, don't think I get more than a couple a week. But boy are they annoying.
Even in such a mobile browser where all the videos are muted by default, these ads find a way to conveniently unmute themselves and delight your surroundings with loudest and cringiest lines/tunes.
YouTube must be actively making changes to their ads in attempt to bypass ad blockers. However, I still think that Brave is a great option as (based on their forum) ad filters are constantly being worked upon.
PS: I've also tried Firefox Mobile with uBlock Origin addon. As expected, ad blocking works just fine, but page loading times are way slower compared to Brave which is based on Chrome.
