Why is my sync account being logged out automatically every day?

I’ve been having the same issue ever since the last update. Microsoft has managed to infect its browser with that nonsense of automatically logging users out of their accounts on its terrible websites. They have a habit of messing with things that work just fine.

I miss the days when both browsers and websites in general would log users out of their accounts on a whim, when they’d push out shallow designs like corporate promotional sites, and when it was easier to reach customers.
