Well it's even worse than that, as I remember hearing that even before these double cameras.

This is mostly because you can blur images in photoshop, and they're assuming the background is just blurred in photoshop. I remember how I had read some photography articles online recommending simple tricks like "Take the photo a bit lower" and "Use aperture which produces the desired bokeh".

Comments were on level of "Haha so just kneel down and blur the background in photoshop? terrible tips!"

Also, the double camera bokeh is no good. I hope nobody spent too much time of their life when engineering this "feature".
