Must pay before printing or saving, but after you have finished
There are plenty of free PDF editors online. I decided to give it a try. Finished editing my PDF, it told me I have to create an account to print it. Fair enough, that's what I do, but THEN, they tell me "oh you actually need to buy a subscription to even print your already finished PDF; yes, we will give you a 30-day trial, but you still need to give us your card information". That's predatory.
