Intentions are frankly invisible and unknowable. 

IMO (though still not knowable) the primary intention of the whole ordeal was restoring Ned and Dan's accounts after they lost them by being extremely irresponsible. The primary cause of the loss was not a bug, as such (broad category of) bugs were entirely foreseen and even expected, and may well happen again even now. It was irresponsibility on the part of Dan and Ned. All of us at the time, including you, were well aware of the importance of using a posting key to access the web site with large accounts, and not an owner key.

The 'property rights' of those who were not irresponsible and stood to lose (and probably in some cases did lose) as a result of their actions were considered less important by an unaccountable central party who decided thus unilaterally and without even giving witnesses as chance to balance the competing interests. That sort of unilateral authority and action (which still exists) is a bigger existential threat to the blockchain than a broken web site leaking keys which never should have been put in the web site in the first place.
