It was as clear as I could make it with the information available. The answer is somewhere between your two hypotheses. Lots of data is no longer accessible, and links are broken. Uploads are safe but some other archived data is gone. There's more to an internet archive profile than uploads, so I'd say it's somewhat serious of a situation. We don't really know the true extent of the problem but we can easily see what's missing (see the lists in the blog posts)
