DVDs have one set of hard-coded keys which were cracked and published a long time ago - to revoke or change them would have required replacing or manually 'updating' every DVD player (not a viable option.) The IP holders learnt this lesson well and so Blu-ray has mechanisms for revoking/updating keys and certificates. Just because the DRM algorythm is public domain, doesn't mean the keys are generally available.
It's not a matter of piety and purity - VLC have decided not to get involved in the key revoking/cracking/resetting cat-and-mouse game, that's all. There are places you can find to download key files to use, but the legality of doing so is doubtful.

Interesting topic :)
So why is VLC Windows allowed to get access to these keys but not VLC Linux?
VLC for Linux *is* 'allowed' access to the keys, if you have them - it just doesn't distribute them.
I have trouble to imagine, that Microsoft is paying fees to all the BlueRay producers...
The license fee would be included in the cost of Windows (or OSX, for that matter)... or maybe they come with a Blu-ray drive, or via some other route. Anyway, I'd be surprised if M$ doesn't own at least some of the relevant IP, in which case it would be under some cross licensing arrangement or other. The license fee doesn't go to the Blu-ray producers, it goes to the owners of the IP defining Blu-ray. The production companies have to pay it too (and thus the consumer in the cost of each disc bought...)
