Yes you are right.
But keep in mind that music institutions have made nothing to balance the situation. They raised the standards instead.
No talking, no clapping at the end of a movement ( are we kidding? ), no casual dressing, no sneezing ( are we kidding, again? ) , ecc.
The anormous amount of formality that goes with classical music has contributed to kill it, and this is why people need to discover again that music is a pleasure, not a formality. They MUST have fun, feel emotions or whatever they want, when they listen to classical music.
You talked about radio. Just go on youtube and give a look to views each piece, new or old, has....they are tons! This means people love this music, but the problem is that performance standard and formalities killed the interest in live concertos (as listeners and performers ).
Musicians must be able to show people how much valuable live performances are, then a flat recording. And we should make this with two things.
1) We should avoid as much as possible sample libraries. They kill everything...performance, music, job....literally everything. Once we accept releasing our music as tracks, on spotify for example, we lose a big part of our music nature...the goal to be played
2) We should create local communities to enjoy music, even our own music. In order to do this, the music should be comprehensible ( as written in the upper post )

Technology is also a big deal for every kind of activity...people used to read, create things, paint, play, just think or even ( appearently ) nothing...now they have full pocket "entertainment". And I am not referring to smartphones, I am referring to social media on smartphones.
