I'm not sure this is such a bad thing that Tidal started doing this last year. This gives Tidal listeners a better listening experience via streaming by applying their "album normalization" thereby helping to quash the Loudness Wars that historically have occurred during mastering. I feel this benefit outweighs individual complaints incurred when toggling between system component sources; the streaming experience is better and I don't think we should expect Tidal to be focused on anything beyond that. This is just my opinion, and like you say, there is a very easy disabling toggle in the app.
