Adobe runs what must be one of the largest deceptive rebills. The vast majority of users signing up for a monthly plan do not realize that it is actually an "annual plan, billed monthly" and thus that if they cancel after one month (for example) they'll be billed for the remaining 11 immediately. I honestly don't know how they haven't faced FTC action for this, as it's been their primary model for 5-10 years now.
We successfully stopped paying for a collection of Adobe products that were for a student license last year. We randomly were charged again in January and February of this year and when I called they couldn't find any records of charges. They recommended contesting the charges on the card and we've not been charged since. Still, crazy that they couldn't even verify they charged my card.
I will never do subscriptions. As you mentioned, the fact that you you have to "successfully stop an automatic payment" is an experience that I'm not willing to go through.
