It's a subtle form of propaganda. Same category as the "funny russian car crashes" or "awesome chinese acrobat" videos that are on reddit's front page all the time. One might wonder why it's always those two countries and not others who are getting thousands of upvotes.

The comment I criticized falsely implies that there is due process in russia, and that technical faults lead to unfair results for the people who are accused of something.

It is a cherry-picked example, and the big majority of russian court cases are decided without due process, because it is a dictatorship. If you try to get justice because you were harmed by corrupt officials or the tzar you're out of luck. Lawyers are getting shot on the street as a birthday present for putin. There are lots of examples. And once you're in prison they'll send you to the frontlines to murder Ukrainians.
