In another story, I needed Lightroom for about a week to do some photo work. I started with their subscription for the month and I wanted to let go if I'm done in the first month. While trying to cancel my subscription, I realize I can only do that after paying for the remaining 11 months (rough calculation). With no other option, I paid my penalty and left Adobe for good. I have deleted my 15+ year old Adobe account…
So you signed up for an “annual subscription billed monthly” (which is discounted from the monthly subscription), didn’t actually read what you were buying, and this is somehow Adobe’s fault? This is not hidden from buyers. It is quite clearly stated when you choose your plan. You committed to something and didn’t follow through, so you are in the wrong.
It's fairly logical: the customer agreed on 12 months. An additional fixed term requires a new contract/agreement. In practice companies now try to keep customers. Plus need to actually be ok instead of relying on people not overcoming the fake effort that is required to leave.
