I guess not , but I like to read other people's experiences. And I'm willing to stay in such places if someone else is paying.

I suspect that if someone has a subpar experience in an expensive hotel (as reported for the two 4* or 5* Japanese hotels mentioned in the thread), someone might think that the only solution is to spend yet more money, rather than expecting that the quality might actually be better at a lower price. That's assuming they haven't had experience with lower-price places, and expect a more or less linear correlation of quality and cost.
