Holy crap, the amount of hate in here, and no actual description of what it does. It's essentially your normal home feed, but only the videos with thumbnails of the selected color. It's also way over at the right of the home feed filters, so it isn't like it's being shoved down your throats.
I care because it shows YouTube is more interested in wasting resources on dumb, pointless features rather than fixing various problems that have been plaguing content creators over the years
The resources used to implement this aren't the same as the ones that would be used to address some of the other issues, as the ones I know of are more social/legal ones.
I bet this was mostly done by a single coder who showed it off and management thought it was a fun thing so added it to the main site.
At this point I feel like it's intentional, and either way, am not surprised. Unlike a lot of other commentors here, I don't see the point in wasting mental power on worrying about it.
Yea, seems like a fun and quirky feature, but unfortunately I don't think there's anything big tech companies can do at this point to turn things around with public opinion given how utterly egregious their other sins have been (and continue to be).
