There has been a lot of attempts to discredit their multisig system to convince people not to use it.
To sum it up: Escrow itself is the protection for customers, but in central escrow vendors have to risk their money being help by an anonymous third party.
Multisig is not for customer protection, its to protect vendor money while it is escrow. So both parties can be protected.
Timelocks let vendors know they will get their money if they ship and item, so they are more likely to ship items in emergencies and keep a good relationship with their customers. The vendor only gets the timelock transaction after they ship I believe.
Timelocks for customers only exist in the case where a customer places an order but the vendor never logs in to ship it. It makes it so funds never get lost forever.
Providing multisig makes more vendors willing to do escrow making everything safer for everyone.
I think that more threads about the same escrow option on the same market would be redundant from this point forward. It's actually better than central in that the market cannot make off with the stash at will. So its not the exact same, it's better, but no it isn't perfect and there are all sorts of corner cases that might in theory result in someone losing an order or profits from an order, but how that means the status quo should be upheld is beyond me and frankly is a fucking insane point to try and argue.
