Good, I'm glad you asked and didn't just take my comment for granted. That is what this should be about.

If you reread the Daily Beast article a bit more carefully however you will notice that neither of the employees mention a walkout. They only give their opinions on the matter. This is another common and rather fallacious journalism trick - make a bold headline and then throw in there a few sources that talks about the issue peripherally. To a casual reader, their brain automatically makes an assumption between what the source says and the headline and legitimises it, even though they are completely separate points. Here, the employees say they feel bad about Blizzards actions, and the (possibly false) assumption is that the employees acted on those opinions and walked out.
