I LOVE YOU NEXON (no sarcasm)

I see this as a bad thing, because now hackers will find it even easier to gift themselves stuff with your NX.

Pointless fear. All they have to do to get all your NX is use MTS to make themselves an offer and accept.
That's far simpler than gifting and gives them actual value to spend as they choose.

If someone gets hacked or their account stolen, I can guarantee that it was their own fault, at least partially.

This was untrue during at least 2 periods last year where it was possible to trick the system into thinking you were another user. They might not have been able to keep your account or change your info, but they could certainly take your stuff that wasn't locked and spend your NX via the unsecured ways like MTS. Now that the client debug info is leaked again we can look forward to more fun exploits being uncovered.
