The energy drink company's interest is to minimize its cost. Years of bad behavior in this regard eventually led to pure food/drug laws, but in places with weak rule of law plenty of people are still poisoned by dodgy food.
Oh yes, absolutely. We have laws banning outright fraud, setting minimum food safety standards, a lot of rules about packaging and labelling. And that's good!

If I want to spend my rent money on 87 large pepperoni pizzas, nobody is going to arrest the guy who took my order because he didn't sit down and have a 30…
They are a servicer, not a lender -- they are contracted by the lender to collect the money from the borrower. So the borrowers never asked to be customers of Navient. They borrowed some money from a bank or the government, who then contracted Navient to service the loans.
Now servicing loans is like owning an interest only bond -- you get a small payment every month as long as the loan is paying. When you own servicing rights, what you want to do is for payments to drag on for as long as possible -- since you don't get the principal, having the loan pay early is the second worst thing that can happen.
Now its very possible that Navient is doing things which are not in the interest of either the borrower or the lender, but are in the interest of Navient. And it's likely perfectly legal.
But again many of these loans are not just simple transactions in the marketplace, but rather subsidized social programs, where the government in promoting the program has a reasonable expectation that some part of this subsidy should fall to the borrower, and is reasonable frustrated when a provider whom they have hired tries to prevent this.
