As far as I can tell from a quick skim, that article is about firing cluster munitions into populated areas. I think we can both agree that this is a war crime and the people responsible should be in prison. I don’t think it would have been any less of a war crime if either Ukraine or Russia had been firing conventional munitions into populated areas, though. I also don’t think it has much bearing on Ukraine’s likely actions in this war, since it’s a conventional war rather than an insurgency with most fighting taking place inside major cities - even ignoring basic decency, there is simply no reason for them to brutalise their own population that way. I was more interested in evidence of a defensive use of cluster munitions which hadn’t been properly cleaned up, which was the direction of the conversation to that point.
