This is just my though.

I read forums in french and english language.
Not about one brand but all just by curiosity.

There are peoples who buy a product feel happy and never look back nothing new.
some will try to find something that could change the way they hear music from a sound reproduction system.
So they buy new products and sell old one.

It's a choice.

Other peoples will look at a brand topic and add comments about design,technics,everythings they would like to see implemented.
They can do it.

If engineers give on purpose tweacks for them will they buy products from this brand again ?
I dunno i'm not them.

Now you all explained it well
There is a big difference between bashing/trys to destroy a brand and learning audio experience by:
listening products.
Asking questions about experience with products.
looking for positive/negative strenght.
and giving/receive advices.

If i dig infos on blu-ray.com
it's leading to a silly talk-show.

It's really rare something like this happen.
