Somebody reposted the link in the OP and I commented also about Pavlik. The thing is this isn't really specific to communism but it did happen a lot in the USSR. It's really just a sign of a bad government and ideology. No child should ever have this put upon them in any decent society.

I'd even argue that this is more reflective of how people think in Britain, Canada and the US now much more than saying it's "communism". Most normal people have no capacity for open dialogue and only want to silence people who go against their narrative.
