There is a clear explanation in the same thread as to why LizardNSA's actions of adding bandwidth to the network isn't good, and in fact, potentially dangerous (not very dangerous at this moment of writing):
The kind of person whose sense of moral outrage gets activated by such nonsense bullshit doesn't know what the word "miscreant" means, and by not mentioning "terrorists" they're just confusing their target audience. If you don't say "terrorist", how are we supposed to know you're the good guys?
"> Only hackers, miscreants and pedophiles use Tor." you must be a full blown moron. Tor is used by journalists, bloggers, gov employees, chinese dissidents and all sorts of ppl in peril. go shoot yourself
> Why? I assure you, our exits are just fine. What's with people responding so negatively to us donating 360Gbit/s of exit BW?
EDIT: From @lizardmafia:
> To clarify, we are no longer attacking PSN or Xbox. We are testing our new Tor 0day.
> Only hackers, miscreants and pedophiles use Tor.
