The linked article doesn't even come close to suggesting money laundering. It really just argues that Wikimedia is similar to virtually every other successful organization on earth and that its bloat grows with its resources.

Wow insightful.

The mere existence of The Mythical Man-Month or Peopleware does not prevent this behavior. Turns out it's actually super, super hard to avoid. It's pervasive enough to have several books written about it, and several more angry blogs written about specific companies' failure to achieve the allegedly "easy, obvious" thing that very, very few companies actually succeed at doing!

Makes me wonder if it's not so obvious or so easy... hmm... Nah, probably everyone else is malicious and/or stupid.
