Huh? What does halting trading has to do with compromising decentralization? You do know what "decentralization" mean right?
They're now talking about essentially blacklisting the hacker's ETH address, how is that decentralised? Halting trading is a show of force too, if they believed a single thing of what they preach they'd let the free market continue its course with the hacker walking away with the money. Looking at your comment history it seems clear you have an agenda here, so I'll ignore the ad hominem.
Decentralisation does not preclude "force". The one really has nothing to do with the other. Unless your idea of "decentralization" is actually the solipsist view that every person is an island, and social structures hold no benefit for survival.
