Just because they benefit from stupid people is not adobe's fault, when it is this clear, people should really be careful about just clicking things and signing up, it's the individuals fault, people or companies are not your friends, this is the case for everything, it's just the way the world works, getting mad at that and then blaming the individual is stupidity and lack of personal responsibility.

They want to charge you as much as possible and get as much money from you as they possibly can, you want the opposite, the end result is something between the two, it's on them to reach there goal, so it's on you to take care of your own money and what you do with it.
