I know! There is a penalty for canceling Adobe's plan, which is ridiculous!
I subscribe to the "Photographer" plan (20GB) for $68 (HKD) per month. It offers a bundle of Photoshop, Lightroom, and Lightroom Classic. When I tried to cancel it, Adobe asked me to pay $408 (for six months) for "pre-cancellation fees".
You can use the Creative Cloud website to talk to Customer Care Services. I then said I would cancel my plan because my team offered me another plan (which they didn't). And Adobe canceled my plan for free within a minute.
