A Bitcoin core dev, doesn't know how to properly store his coins. Doesn't have over the top multisig setup. Doesn't at least have legit control over his coins and not just a few but 200.

And if it is legit, failed to follow the most basic principles of Bitcoin security (not referring to multisig and cold storage just basic custodial principles). And deserves to learn the lesson the hard way IMHO. He's a huge reason why there are so few wallets that have Paynyms BIP47 and other privacy features. He's an enemy of Bitcoin privacy. And it's apparent with his lack of understanding basic privacy principles.

Are we sure it’s a “hack”

Im about to get real tin foil hat

I think Luke did this so bitcoiners can think "if it can happen to luke it can happen to me" then hes gonna champion custodial solutions, to which he has a backdoor deal with one or many of them.
