(Google punishes viewers who make themselves less valuable to advertisers by giving them an entirely blank homepage.)
The era of Google providing costly features to users with no benefit to itself is coming to an end.
One wonders if you couldn't whip up something that would whip up a list of choices by operating locally only on the users history returning just a list of things to show on the page and forgetting it when the user closed the tab.
As for what they should do, I think populating the homepage from the subscriptions list (either literally as an ordered list or by some algorithmic "watch time vs average watch time for this creator", I don't care) would be preferable.
Most users won't understand how that works. As far as they're concerned "youtube watches what I do", and any explanations about how the algorithm runs locally but google can still see what you watch if they look at IP logs will be far beyond a typical users desire to understand.
I’m under the impression my use of private tabs & blockers & iCloud Private Relay is nearly useless when browsing sites of any sufficiently large company, and I won’t lie and say it’s not somewhat frustrating and disturbing.
If the goal were anything but discouraging disabling watch history, they’d take care to design a page not so strikingly barren.
Video categories, subscriptions, trending searches (not saying we’d WANT that), Google-curated selections, recommendations based on user choices (“what kinds of videos should we show you, want daily news/sportballs/music recs?”)
