Other than generally Amazon doing layoffs my guess is interest in equipment that they talk about has dropped greatly and specifically because of smartphone cameras (Iphone in particular in my case). I have an expensive Sony Camera (several thousand for the body with a $2000 lens and other lenses) and haven't used it in years. I just use the Iphone. And I am someone that had a darkroom years ago and really enjoyed photography (and made money selling pictures even). It was a big deal to me to take pictures. But it was more exclusive since most people didn't have a professional camera.
Photography has changed in the sense that back when I did and enjoyed it there weren't any digital aids or easy ways to make pictures look good. Or be able to just take as many pictures as you wanted in all sorts of light conditions. And that was actually part of the fun for me. I mean even my Sony camera can't fix pictures like the iphone can on the fly.
The iphone (I've had all of them now an iphone 14 pro max is what I use) is just good enough to provide enjoyment.
