Seriously, what the fuck? I thought it was some kind of user interface glitch so I looked it up. Nope, they're A/B testing this shit.
Found this brilliant statement by Youtube on the matter:
Now note that we are deprecating one sorting option and that is by oldest video at the channel level. But don’t panic, you can still view the oldest video of a channel, by scrolling through it’s content’
Oh, yeah, just scroll to the bottom. Silly me, I guess I'm just a stupid idiot for not realizing the option was redundant since I can simply take the time to scroll through potentially thousands of videos.
Why are silicon valley tech people such freaks?
Any time you're scrolling, you're seeing more content and viewing ads for longer. The goal is to make YouTube as inefficient to use as possible.
I actually didn't think about this because I've never seen an ad on YouTube and never will. The day ad blocking dies is the day I walk away from the internet.
Then I pray it dies soon so we may all be free.
