The way they respond to developments such as this proposed attack by Anonymous may not necessarily make sense to them or to others.
We know exactly how it'll be interpreted: Satan is attacking us!!!
BTW, Anonymous doesn't care about causes or "saving the children":they are not an outlaw band of renegades out to make the World a better place, or right wrongs, etc. There's no organizational structure (think of like Al Qaeda, with loosely members connected only by an ideology), so there's no GB to lead/prosecute. They will engage in attacks that are often contradictory, or done only for "the LULZ" (done purely out of joy of watching the chaos they can cause).
They could care less about the damaging outcome of their public disclosures: that's not their concern, in the least.
I followed the Anon attack of some security firm (can't remember their name, but they had claimed to IDed Anon members) a few years ago on Arstechnica (a website that has excellent coverage of Anon-actions), and the fact is Anon's public disclosure of wrongdoing actually renders some evidence as inadmissable in court, since the defense can complain that the information was possibly tainted as it was outside of their chain of custody.
So Anon's actions are NOT always a good thing, if you're looking for your justice in the form of that kind delivered in a court room, and not simply as a public spectacle done trying to embarrass potential defendents.
