I used the trial period because I needed to edit the one pdf I would probably ever need to. I was editing it over the course of the work week and after finishing I forgot to cancel within the week. I thought it was no big deal I will take a $15 hit for the month subsciption but no. If I want to cancel I have to pay an additional $30 because it is a year contract. GFY adobe, this isn't a gym membership.
It isn't a mystery why there are so many related conversations. Subscriptions for software should NEVER use this structure. I am not saying they hid information or did anything illegal. I am just saying they are scum for structuring it that way.
