YouTube needs a history-less mode. I want to watch random videos without them impacting my recommendations. I have Premium, but I'll use ad blocker in a private browsing session specifically for this.
But yeah, the incognito mode is bollocks.
Some of my recommendations are based on my subscriptions (but only directly), others are just random things based on my location and language.
But even self-curated history and other tips I’ve got here still produce an echo chamber. Even “New to you” tab which appears once a month for few minutes becomes too narrow. I gave up recently and removed youtube from my bookmarks bar, to suffer less often. I find the idea of paying for it pretty… strange?
Browse in Incognito mode.
Better: access through an Invidious or Piped instance.
