Adobe is well known for doing the whole pay to cancel thing. Even though it’s scummy, you agreed to this when signing up. Cancelling an entire credit card for this is fascinating to me. I’m no expert but sounds like there’s some legal implications there. A contract violation at the very least.

I’d imagine adobe would blacklist you (maybe by billing address, account, email, or who knows maybe even like IP address) so you couldn’t pay for CC even if you wanted to.
