Point one: I’m pretty certain they already track that. With or without account. And you’re on the internet, without a VPN there is no privacy. You are also able to remove that history any moment you want. Is it Ideal? No. But you should’ve acted 10-15 years prior if you wanted to stop this. It’s still not ideal though.
Point two: I agree. There does need to be space for them to repent, but they aren’t actively trying to, so don’t trust them (see the next point as an example of that).
Point three That’s a shame. They really need to fix that, though with how corpos do things nowadays, not sure that’ll happen.
Point four: That’s normal, expected and a reasonable business decision. Most of these features they likely added after premium, and they’re meant as incentives. Why else would you want to but their premium, if not for the added features?
Point five: This is shitty and mostly inexcusable behaviour. It’s god awful, and they really shouldn’t do it. I do have to play devil’s advocate a little. They are fully, 100% in their right to do this. If you don’t like it, vote with your wallet (and time). If we stop using their services, they’ll stop making it worse. They are still A-holes for doing it though.
I would be very interested to know how good they are at tracking a user across brand new browser sessions. I have mine set to delete cookies, cache and history (minus a few trusted domains) on close but I’d imagine it would be easy to differentiate between me and others in my household by browser fingerprints alone. The only question then is whether those guesses are reliable enough for Google to essentially treat those sessions as 1 person, or throw it away since there are bound to be quite a lot of cases where 10s or 100s of people on the same IP have very similar browsing habits and configurations and trying to figure out who is who would be incredibly difficult (think offices where everybody could have exactly the same laptop and share similar browsing habits due to working for the same company). That’s my cope anyway. The alternative is Youtube over Tor for which would be painful.
Points 4 and 5 on my end are essentially two sides to of the same coin. I should clarify, I don’t have a problem with YouTube introducing a new feature and making that Premium-only.
