That's a weird site.
I suppose that calling themselves "The Bitcoin Foundation", even though they are not connected to the better-known Shrem Karpelès & Friends Foundation, is their idea of a joke, or a statement of something.
I can't say much about the code. I would have to read more, but I cannot find a more specific statement of their goals. Their
mailing list shows some continuing activity, but rather modest, it seems.
What else can I say? I wish them well. Cleaning code is always a Good Deed, like collecting trash from beaches or recovering decayed neighborhoods...
