The death of Selective Colour and High Key White Background Family Portraits

There are only so many more times I can look at a black and white photograph with a small part of it left in colour before I will break. It is usually something like a flower, a dress or the subject's eyes as the only coloured part of the image whilst the rest is grey scale. 

I understand that learning Photoshop is a very slow and gradual process but it seems that many professional photographers and image editors alike are still ruining perfectly good images by desaturating most of it.Why?

Now this is a perfectly decent macro shot of a ladybird on a leaf. Why on Earth does it need to be made partly black and white? I would bet money that the original with the vivid green against the red wings of the bug looks much better. Why oh why oh why must people do this?

While I'm in the subject of colourless backgrounds, when are we going to see the death of the already 20 years old plain, boring, white background studio shots of families? It's not new, it's been done before and it shows no talent. 

No no no no no no. Enough please.
