This article will be just the tip of the iceberg if the news media decides to follow it. There are more than enough ex-EK pilots who are willing to talk that, should the media be willing, they will have more than enough 'proof'.
I've said before that should EK have an accident that the Guardian or the US tv show 60 Minutes would have a PANEL of 15 or 20 ex EK pilots talking about the issues.
Now, even without an accident, it is starting to brew. With ALPA and the US airlines looking to slow EK etc. this might just blow up.
I'd also contend that the unmentionable airline might not be too happy that EK's shenanigans (too put it politely) might cause them some issues.
