Most of these can be lumped under "I don't like vertical integration". Which to be fair, neither do I, but it's a bit of a misuse of the term to call most of these dark patterns. They mostly fall into the category of things that they were obviously always going to do, because no manager could defend not doing them (imagine someone trying to defend making a brand new account system for this)

You wouldn't make a brand new account system. You'd adopt OAuth login that keeps the accounts linked but still technically separate.

If i login to all services using my 'meta' oauth, it'd make sense that i lose everything that was under that master account. The inverse should never be true, a linked account should be severable if it is the child.

This is absolutely a dark pattern in that context.
