I believe that merchants are not responsible for fraud for certain kinds of transactions, like credit card transactions that use chip-and-PIN.
On the other hand, there might be higher responsibility for card-not-present transactions (i.e. someone entering a CC number into a web form over the Internet, or merchants deciding to accept a CC transaction while their machine is down and can't swipe, entering the transaction later as a card-not-present).
Not an expert on this.
One remark I'd share is that many crypto systems, in their basic transaction form, remove all consumer protections like that exist in the form of chargebacks. This can be a good thing if the merchant or marketplace is reputable and can be trusted to do the right thing. It could be a bad thing for consumer protection broadly though. The fact that you can easily charge-back a transaction provides a sort of lubricant that makes consumers more willing to spend online. You know that if a subscription company makes it really a pain in the ass to cancel, then you have the nuclear option to fall back on.
(OTOH, there's no such thing for subscription payments for blockchain. You'd have to build that custom as far as I know.)
