It's interesting that this take on Russian propaganda is itself a becoming a little outdated - flooding makes sense externally given you have external channels for it and internally, where the channels might be a given but the regime does not want to appear overly coercive. Russia now has fewer external channels than it did in 2016 (your link) and 2021 (posted link). It's more coercive internally and a more coercive (but reasonably rational) regime needs more consistent internal messaging so that people know where the line of trouble is - defining the limits of public behaviour and expression becomes a more important part of the propaganda. There's still 'flooding' but it isn't sufficient.
