I probably saw it, it is too fancy to not be noticed by media. But here it's not the about the hand. Look at sabre's handguard: it doesn't guard anything, it is turned towars the wielder's wrist. So, the ork is trying to imitate that technicque, but does it wrong.
Since "communism is when equality". Starlight's ideology at the first glance is pretty close to strawman communism which is all about not allowing people to be successful (i. e. much richer than most others), and her spell caused cutiemark-related abilities to disappear. But the funniest part is that it misinterprets not only communism (which is about economy and not personality to begin with), but Starlight too, since she believed that different talents lead to different interests and disappearance of friendsip, not that different talents make some ponies better and others worse.
