Basically they disabled anon editing for all major wikias whose primary target audience is children.

IMO this is unnecessary. The point of the law is to protect the privacy of the unaware, not stop underage editors, who can easily create bogus account and continue business as usual.

So basically this an empty gesture, one that could be easily achieved by adding anon edit notice that they agree to comply with terms of use(like on wikipidea) and wouldn't have hurt the more mature editors on those wikias.
