That’s because we are having a meta discussion about a meta discussion. To put it another way, we are engaged in a self-referencing discussion. To talk about such a discussion in solely general terms would render the rhetoric useless to anyone outside of academics. We would have to write in completely mathematical terms.

Again, it’s not laziness, but off topic. The term in essay writing is paragraph drift, but since it would be off topic for the article as a whole a more accurate term might be article drift.

A hypothetical complaint about cat memes not getting mainstream coverage is a meta discussion about coverage not cat memes.

The point about bringing up Concord’s flop is that it in particular is comparable to other media that the mainstream news does report on, such as expensive movie flops, but it still isn’t being covered. Why Concord flopped has nothing to do with that and that kind of context wouldn’t add anything to the article’s central point. The article also uses Joker 2 as an example, but doesn’t go into why Joker 2 flopped for the same reason. Why Concord flopped would be as off topic as taking about Concord’s game play mechanics, while possibly interesting, they aren’t relevant to the discussion either. Just because Concord’s flop is relevant to this discussion doesn’t mean all things related to Concord are relevant.

These kind of meta discussions about media coverage are important as they are a self-examination of a critical institution. A self-referential discussion is its own kind of genre and has its own rules, or guidelines, for what it is and isn’t relevant. So it’s definitely important that people understand that and don’t mistake this useful kind of journalism as lazy. Trying to placate this misunderstanding would render the article less rhetorically effective on delivering its central point. It’s like Paul’s analogy in Dune. He shouldn’t have to cut his dominate hand off to please his space jihadists. That wouldn’t be useful. edit: typo
