Just implemented this! Thanks for posting! For those who don't click, he suggests some uBlock Origin filters to remove the suggestion lists from YouTube. For example, currently I'm watching a video and all I see is THE VIDEO - no list of suggestions off to the side.
I guess we can say YouTube's suggestions are "too good"! I might just apply this to my work computer. I'll probably keep them around for my casual viewing on personal machines since I find some new stuff with them.
It'll be interesting to see how this changes my browsing!
