I had an educational Adobe CC subscription that went from ~£25 per month to ~£67 recently. When I went to cancel after I realised I didn't really use it that much and could just use Affinity, I was shocked to find out that I was going to be charged ~£250 because although I pay monthly I was in a yearly contract. (I did know that, which is on me, but it's easy to forget that because of the payment structure). It's a serious barrier, so I looked at the other options, and you're able to transfer to an Adobe Photoshop Express plan for ~£98 per year and avoid that charge. I figured I'd do that and immediately cancel so I didn't forget to at the end of the year, whether I kept access to Photoshop Express or not - I just wanted out of the Adobe ecosystem. To my surprise I was refunded for both the balance of the month on the CC subscription because of the plan change and then refunded for the entire year's Photoshop Express because I still had 12 months to run on it. YMMV, but if you do it in that order, you can potentially escape Adobe without being penalised for it.
