It's a fact brother, even if we choose not to believe it.
Trades will continue as they used to no matter how many scammers will try (and sometimes succeed) to scam. This trap was set in such a way that nobody (unless he was very lucky) could avoid it and not fall in. Perhaps if the escrow waits for both parties to confirm the changes or to have another way of communication like an extra layer of security measure. Eg. To proceed in any change/ major decision the escrow will ask for both parties to send a "message" to his WickrMe (since this app needs signature to verify the user) or some other. Perhaps some of you guys (since I'm not a techie/ dev guy) in your spare time can create something to use...
Exactly as you say it in your next sentence. We learn, even if it's the hard, painful, crappy way, and establish better ways for the safety of us all.
