Why? Well, it is well known that the equimpment used for playing a file - amp, speakers etc. - was well as the room it is played in has large impact on how music sounds. For example, I moved to a new place a while ago. I use exactly the same equipment (computer, CD-player, amp, speakers, cables) as before, and I often listen to the same music in the same format (mostly redbook CDR, sometimes hi-res FLAC files). But the room where it is placed is very different - smaller, different form etc. I use what I consider to be good speakers and an OK amp. Well, in my old place, the sound was very crisp anc clear - great but just a little too bright for my taste. Now, in the new place, the sound is bassy, almost muddy - not really bad, but definitely worse than before.
Now my question is: HOW exactly would MQA guarantee that the sound I hear (with my speakers and amp, in my room) sounds exactly the same as it was intended to sound by the mastering engineer? Let's just for a moment assume that that would be even possible: what information exactly would the MQA file or player need to have in order to be able to do that? Well, at the very least, it would need to know which amp and cables and speakers I use and how they sound; and it would need to know the size and form and material of the room the music in which the music is played; it would even need to know where the windows and curtains and pictures are located and which other things in the room (like beds, blankets, carpets...) would affect the sound, and how exactly. If the MQA system does not have all that information, then it has no idea how the music played in my room will sound, which means it will be unable to do what it is supposed to do: guarantee a specific sound. Now, when I get my MQA files and whatever other equipment I need to play them properly, does it ask me for all that information?
To be sure, I don't have any MQA files, so I cannot rule out the possibility that there may be something about the MQA format that makes it sound better than other digital files. If that's the case, than maybe they should do a better marketing i.e. explain how that is possible. What we can rule out by pure logic, however, is the chance of guaranteeing a specific sound without knowing anything about the equipment and environment where it is played.
