Obviously. The service provider will shut down an account if it is not paid or charged back. That has nothing to do with malpractice, that is practice everywhere. If you want to charge back you need a backed claim. Just saying "I have the right to do so, because reasons" does not make it true. Bioware will also not close the account on "refund demanded" only on "charge back", which is fraud in the eye of the service provider (you want to use the product, but not pay for it).
If you do NOT want to use the product, you can cancel the account, then you are also not paying and you take the legit way to "vote with your wallet".
This line of "argumentation" sprinkled in between legit claims is part of the issue that makes seeing your posts as troll posts easy. You claim to know a person that seems to be getting migraine from playing the game. That seems to be a real issue. And then you HAVE to prove, that bioware is some awful company by framing standard industry practice as mapractice or somesuch. Let me explain:
"Yesterday I went to McDonalds and bought a coffee. But they overheat the beverage as of late, without telling someone, so I got 3rd degree burns on my hands. I then did not pay for the coffee (because of the injury) and they had the gall to not let me leave? They even called the police?"
Edit: since it seems to be /whooshing over some heads. In the above example "I" did not pay for services rendered, so the store is in its right to keep "me" from leaving. Simply stating "I do not need to pay, because I burned myself on your coffee" in the store, does not make the claim in itself right. Yes, I could afterwards make my damages heard, but without "backup" I have no right to just refuse payment. That also would be true for the case of the diabetic, even if bringing this up as an example is overly dramatic.
Keep the argumentation to the original point and it is worth discussing, but tin-foil conspiracies help no one.
