Totally agree!
We start off with superb performance and then the dead hand of the accountant reduces it to rubbish. Happened with LP > CD > MP3, then FM > DAB (High Bitrate) > DAB (Low Bitrate), now HD Hi-PQ > HD? Poor PQ. The problem is, the discerning listener/viewer is outnumbered by the uninformed majority who happily accept 2nd- and 3rd-rate quality.
Just like most things in this world, progress doesn't necessarily mean better!
