I don't quite know how to categorize complaining about pseudoscience based on a "vibe".
It's not quite irony... maybe it's just humorous. As a member of the post Alanis Morissette generation I guess I can no longer recognize irony.
There's a lot of 'wow, isn't that interesting' talk and deference to authority on an 'important' issue, but little talk of the actual mechanisms of how things work, little consideration of obvious counter examples that could be an explanation (like the one in my comment).
The sense is that the argument is driven by motivated reasoning instead of trying to understand what's true. Basically starting with a position and forcing the data to fit your pre-existing position.
It feels like I'm being conned by someone making up bullshit for status or some other agenda (maybe just sunk costs into an existing theory). Often bullshit and complex interesting topics can sound similar at first and it's helpful to have some sense for telling the difference. Otherwise you wander around impressed by 'energy crystals' and worried about 5g.
For example: I think X is true, I cherry pick data to back up X and publish a book on it. This book gets a lot of attention and is good for my career, but it's based on bad science and misleads people. This is a theory I identify myself with along with my success and my own career, if its ideas are invalidated that reflects negatively on me and my abilities (and potentially the ability to support myself). There's an incentive to rationalize or continue pushing the bad science which slows down figuring out what's really true. This has happened a ton of times throughout history.
In this specific situation the benign case is people sleep more and it doesn't matter (or it helps), in the pathological case people are anxious about their lack of sleep and it negatively effects their life or they sleep more than they personally need and it turns out over-sleeping is co-morbid with depression and causes other issues.
In the general case popularizing bad science has knock on effects that make it harder for people to get funding to study ideas the contradict the popular, but incorrect zeitgeist of what's commonly thought to be 'true'. It can also lead people down rabbit holes that can take a long time to crawl out of and make it take longer for people to understand what is actually true.
You can't just hand wave this away by saying "I know X is true, therefore it doesn't matter if the data is a little problematic. X is true and it's good for people to know that". A lot of times X turns out not to be true, not to be entirely true, etc.
For example, as it turns out there is little evidence that stretching actually does anything, yet a lot of experts used to recommend it for decades. Same with nutrition, 'balanced diets', workouts at low heart rates and so on.
it actually has negative impact on health and injury in people who do static stretches in particular is significantly increased. (as is in people with high levels of flexibility in general)
Nowadays stretches as a warmup are not recommended any more.
