I wrote a detailed article about it, what every developer should know about software subscriptions and civil law: https://thehftguy.com/2020/09/08/what-every-developer-should...
Epic doesn't allow a civil law process, they force arbitration anyways. So the deck is stacked against you
Epic doesn't get to set the law, the country where the consumer resides does. France for example operates under civil law and arbitration clauses are void (in consumer contracts not in B2B).
Users should ask for refund and charge back if they can't get a refund, preferably keeping a paper trail of the requests. The legal details are only relevant if one goes to litigation (this sadly happens regularly for example with children bankrupting their parents with in-game purchases).
Do you think that really matters to or is realistic for the average non-technical user? Heck even as technical user I don't want to deal with that crap, I want 1 click unsubscribe which I get through App Store subscriptions.
