It was a shock reaction image that became popular on r/cth and kind of became a mascot for the sub & then later for chapo.chat/hexbear.
Honestly, we all got so used to it that it became a nothingburger internally, just a way to tell someone to eff off. I was surprised to see it actually affecting people post-federation, but that's also attributable to the emoji bug.
I don't understand the logic here. When the putsch occured and then ignomously fizzled out, I saw Putin as weak for letting Pringles walk out with a (relative) slap on the wrist. Taking Prigo out of the picture was overdue. Obviously, anyone would feel threatened by an semi-autonomous mercenary army, so removing its leadership and breaking it up is just a rational course of action that probably should have been done sooner from that POV
