Minidiscs proved that people were comfortable with lossy compression. It was to be many years before lossless audio became a thing again.
It always amused me how we were told the difference between lossless and lossy compression was undetectable to the human ear up until the big streaming services started providing lossless and even high res, at which point it was suddenly the best thing since sliced bread. However you feel about the audio, one way or another it's gaslighting.
Personally, on most music I can't tell decent quality lossy from lossless, but I listen to a lot of choral polyphony and also perform it so I have a good ear for it. When you're listening to 16 or in some cases up to 40 voices and can follow individual lines (single voices recognisable as particular people) you can hear it, and I disliked minidisc and mp3 players for that reason. High res, though, makes no difference at all as far as I can tell.
They did no such thing. Sales numbers were tiny outside Japan. People only tolerate lossy compression when that’s all they are offered. Hence the streamers introducing lossless options years after launch due to demand.
