First article is an excellent resource.
It describes how to use inexperienced workforce and apply brute force motivation so it would actually work.
It's based on an idea that amateur artist can screw you over and sadly it's mostly true. So that's what's it all about and methods do work.
While I wouldn't work under such anal circumstances (tbh, I DO WORK like this or even worse, but for my employer of big company, not some indie flash game dev), I don't really see anything out of line. Welcome to capitalism.
Getting most bang for least buck is an idea as old as human civilization. Every professional artist knows this. Maybe amateurs don't and that's what caused such outrage.

Second article is all about being butthurt, however, there's fair share of good points there.
