All I see in this article is systematic discrimination and abuse of an ethnic minority by the Han. It makes no mention of any militant organization, but it is a great example of how they develop. Yeah, cultural and ethnic discrimination in a region that was militarily annexed by the very ethnic majority that abuses them will breed anti establishment sentiment in the population. That is not a purely Muslim phenomenon, nor is it entirely unjustified. Being told to just accept that you must integrate into a new nation where you will forever be a minority stigmatized for your cultural background is very worth resistance as far as I'm concerned. This article even outlines how Uighurs are forced to do things that are directly opposed to their religious beliefs and effectively make them sinners. I'm not sure what you see in this article that I don't, but if you're opposed to ethnic minorities rioting against systemic abuse then I think we're not on the same page.
