Adobe pioneered the "click cancel plan but we will offer you some stuff that you don't care about in order to stop you from cancelling your plan" dark pattern.
Then on the support call they will straight up pretend that none of their systems work in order to stop you from cancelling.
I have literally cancelled (and later re-obtained) subscriptions to CC at least 15 times. It hasn't been an issue, and I've never needed to call anyone.
They do offer you things, but those things tend to be free months. Not random stuff you won't care about.
If I'm trying to cancel I don't care about free months or free storage space or discount on their new product. those are random things I don't care about.
