It's very common that various corporations have very lengthy terms of conditions that hide a lot of nasty details that can screw people over. Of course people typically do not read that.
One big issue is that it doesn't take much to enter into a contract. Just buying into some service can for example allow them to force you to pay more for it because you didn't actively cancel in time (such as 30 days before the renewal date). They can even renew it for a much higher price than if you do not pay attention you can lose a lot of money (in the fine print it will say it's your responsibility to check your email, etc).
You can basically ruin your life by signing a single bad contract and signing a contract is very easy, you have to be constantly paranoid about corporations and others trying to screw you over.
