What would the problem be in just showing a button that says "Confirm unsubscribe" that sends a POST request? A lot of sites does something like that for their newsletter unsubscription.

I like the one-click URLs though. It irritates me to no end to click unsub, then wait for a page to load then repeat my intention.

I'm actually much more concerned when I don't have to click the link. It let's me know they haven't thought the problem through and what other errors and problems are there in their systems?

That would comply with GDPR, and is a valid solution.

It is at least better than asking the email or something even to login to unsubscribe ("update communication preference")

I believe asking to login violates the CAN-SPAM Act. That being said, there might be two links, one for "update commication preference" on top and "unsubscribe" in small text at the bottom. I always ignore the first and seek the latter.
