I'm the OP. For the record, people on my team do review PRs. And we typically do assign PRs to people in github. It's just that we don't have a very structured process beyond that, which leads to some mildly annoying ambiguity at times. I'd say the situation is basically what sethammons described in a sibling reply. That said, I really appreciate your comment. It seems like a lot of other people have faced similar issues with CR, and I'm sure some people are facing a situation where teammates resist reviewing PRs. Also, game theory is a great lens through which to look at the situation. We probably could incentivise communication around CR better.
