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.
