The gist I got was this - Wordpress was working on this in open source. Wix took their work, built on it, and didn't make their contributions open source, taking advantage of the repository and giving nothing back.

Which is fine if the code was BSD licensed, but the article states that Wordpress uses GPL, hence Wix may be violating the license regardless of the breach in attribution etiquette.
IANAL, but their private fork (I couldn't find a public one on Github) is also technically permissible, as it's not a redistribution of the code.
Edit: if what's in question are strictly web assets (images, js, etc), then I'm pretty sure, but not certain, this is a violation
Why not opt for a BSD license? The things you wrote also apply to BSD licensed open-source software.
Edit:
I agree with you, but I was mentioning GPL because you placed it in question. BSD is great, MS-PL is a little nicer if you need to protect any patents too.
How much would that cost? A few hundred thousand?
