Tidal's end is an inevitability. It was bought to be sold. But Jay-z I think missed the window and the broadband/tech/media world is in the middle of some major changes. Someone posted elsewhere the market share of these services and all but 3 - Apple, Spotify, and I forget the third maybe Pandora - have miniscule market share. The smaller services simply cannot sustain over the long run. They will shut down or be assimilated.
Tidal in particular has been heckled unfairly from the get go, but I think the end goal was always to sell it at a huge profit just like Dre did with MOG, which became Beats, which them got bought by Apple for a billion. Jay-Z made a smart play, but I think his timing was just a little off.
Deezer isn't going to fare much better. They supposedly have hi-res but as I understand it you have to some sort of 'partner' brand that will allow playback. So that shows you the model they had to take to not lose money through the nose.
Make no mistake, in the US consolidation is rapidly underway and hi-res is not a priority. And with zero transparency, you don't even know if you're getting true hi-res anyway. So hold on to those CDs and SACDs. Our international friends however, will continue to enjoy great services like Qobuz. The trends have been clear for years.
