Basically what I am saying is that putting stuff in writing projects them from frivolous lawsuits. It also prevents WT from reneging on their obligations if the applicant is not in breach.
This is just basic stuff.
I dont see anything in that contract that is of any benefit to the person signing it. You say volunteering is a two way street, I disagree (especially when it comes to this particular contract). Sure, they don't buy their own groceries etc but then neither do prisoners of your local penitentiary. Do they get to choose when/what to eat? Do they get to go home when they want? Do they get to mix with who they want? It's like the negro slave on the plantation say "we got it good here, we don't have to buy no groceries".
