any extremely long contract with obtuse terms is designed to screw you in some way. you just wont know until you get there, unless you are willing to spend 10-20k on lawyers to argue the terms
This is not true. There's plenty super friendly contracts that just happened to be written by lawyers who are into legalese maximizing. I can imagine that someone trying to screw you over might use obtuse terms to hide that, but the reverse isn't always true. Sometimes things are just obtuse for stupid reasons.
