As was already said, Apple has limited the scope of the NDA considerably.

The NDA only applies to registered developers anyway, though. Additionally, this year anyone can watch all WWDC videos (discussing much if not all of what is mentioned in the linked article). The general public that can just access the page with the WWDC videos (without any login or any requirements to identify oneself or accept anything) is obviously not at all bound by any NDA at all.

Here are the videos, check them out: https://developer.apple.com/videos/wwdc/2014/ (sadly still requires the right software to watch)

I like this new more realistic and pragmatic approach to how they handle their NDA. In the past it was always a pain to listen to actual devs talk about the WWDC because they always felt like they had to be careful about what they said (though, to my knowledge, Apple never enforced that, but better safe than sorry, especially if you make your money on that platform). Meanwhile, everyone else was just talking about it freely, but exactly those people who most likely would have the most interesting things to say were silenced.

There was a blog post about this http://oleb.net/blog/2014/06/apple-lifted-beta-nda/

Further, Apple agrees that You will not be bound by the foregoing confidentiality terms with regard to technical information about pre-release Apple Software and services disclosed by Apple at WWDC (Apple’s Worldwide Developers Conference), except that You may not post screen shots, write public reviews or redistribute any pre-release Apple Software or services.

It seems Apple has reduced the scope of the NDA this year. http://oleb.net/blog/2014/06/apple-lifted-beta-nda/

Apple's releasing more information than usual this year.
