So MQA sounds good enough for some people. Fair enough. It is a split decision on the basis of very little data. So that does not trump all the other problems pointed out by Golden One, Archimago, Jim audiomisc, mansr, and other people linked or referred to in this thread.
On the point of MQA not wanting people to be able to have the choice to decide the kind of sound they like for themselves:
Whenever I buy a newly remastered streamed or vinyl record, for example Patti Smith's "Horses" remaster from 2005, I get really excited that I have access to both the remastered and the original album. This is because that enables me to listen to the album, first the way it sounded originally and then in its remastered version. I can choose which to listen to at any given point in time.
With MQA trying to corner the music market, at some point in the future, we may not be able to choose lossless over lossy MQA for some new albums or even for some classic rock titles.
How to avoid this situation:
(1) Let MQA die as it brings no overall improvement to music playback.
(2) Let MQA live as a filter choice in the digital domain. I am pretty sure that it is not impossible to emulate the MQA process in the digital (or analogue) domain to equalise, sweeten, deblur and enhance dynamics the way MQA claims to do it, even on the basis of lowly FLAC redbook or hi res original sources.
(3) Stick to physical media. Vote with your pocketbook [Thanks to

So make MQA available as an optional filter choice that people can choose to select. Don't drench MQA onto all music, please.
