This is one of the many things the media does - manufacture drama. The story was that PS5 sales were slowing down. So what? We're 2/3 of the way through the generation, coming off a supply shortage followed by record sales.
My understanding is that this gen has far outsold past gen. They are presenting "facts" but in a way that twists them into bad news.
It is the same thing with the economy, they'll not report the stock market going up for months and setting records, but a one day drop leads.
They can't lie, but they can very carefully highlight certain things and ignore others.
