The internetz are ablaze with the news that AACS 2.0 has been successfully cracked using an SGX exploit (not like Smurfs 2 which was due to bad keys):
Patriots Day (2016)
La La Land (2016)
More to come... I can't believe that some people (very vocal people) didn't think this would ever happen. lulz
I'm not talking about rumours, we've heard about this SGX possible compromise for months now, I'm talking about proof that this is what's been used to crack AACS 2.0, which is what you incorrectly posted in your first post. AFAIK there has been no link established between the SGX vulnerability (which will be patched by Intel anyway, which means that unless you have one of the flawed processors you won't be able to decrypt and backup your discs) and the illegal release of a handful of titles by a group of pirates.Given the nature of the sources being all related to piracy, I won't provide any links, but I'm sure if you searched for "aacs 2.0 sgx uhd" with a filter on the last week, you would find plenty to read from multiple reddit threads, doom9 threads, and torrent news sites.
No one specifically knows 100% if it's actually cracked or if this is a different workaround, but the group responsible (in the photo above) is claiming that they have found a way. Tip o' the iceberg, I says.
Until someone publishes code or releases software proving that AACS 2.0 has been cracked (i.e. that any original disc can be read with unlicensed software), it simply hasn't been cracked. It might be partially cracked, or it might simply be leaks of the files without any cracking taking place, just simple data theft. No one knows, as you correctly say in your second post.
Please, let's discuss here ways in which AACS 2.0 prevents legitimate owners from making backups of their original discs. I have no interest in knowing that a group of thieves somewhere can illegally share intellectual property online, and that other thieves are happy to download that content without paying for it. I certainly don't want to read anything about this on AVS Forums, as I believe it's correctly against the rules.
So until we can indeed make legitimate backups of our original discs, AACS 2.0 hasn't been cracked. Anything else should be discussed elsewhere.
