Do you even understand what a protected binary-blob is?  You cannot see what is inside a blob by linking to source-code for a distro.  If they could see what was inside of them they would not need to be concerned with removing them regardless.  Blobs contain executable code hidden in the kernel (that's what I mean by hidden), and it's irrelevant whether both have the same blobs.

What's relevant is that Debian prefer and strive for a completely blob-free system, and you should strive to run one.
