Tidal fraudulently sells lossy upscaled music as HI-RES FLACs (2018)

This post is a year old, and it seems from the comments that it might not have been a Tidal problem and instead something from the source, as similar problems appeared in the MP3s from Google Play and CDBaby.

I'm not a huge fan of Tidal's "master quality" MQAs though, which I don't think are actually lossless even though they're advertised heavily as being the original master quality. (MQA stands for master quality authenticated, and the MQA site is full of technobabble about folding the file to make it smaller (10% the size!) and then unfolding it one, two, or three times depending on your equipment, etc).

The reddit thread is over a year old, does anyone know what has happened in the meantime? Did the users get their refund? Are they still doing this?

The title should be tagged [2018].

That is a very honest spectogram. On the positive side, this is yet another resounding victory for psychoacoustics and the human model of hearing, since it seems that the average Tidal user didn't notice this problem merely with their ears, and it took a spectogram to be sure.
