This only applies if you somehow are only exposed to music that is played on the radio. The same type of people who don't connect with current popular music probably didn't connect with previous popular music. Many people largely disengage with seeking out music once they enter adulthood, if they even did to any meaningful degree at all. They might still listen to music they liked when they were younger regularly, but they aren't going out of their way to discover it. My parents are in their 70s and were never that into music. My dad kind of liked the Beach Boys, but if I asked either of them to name a Beatles song they would struggle as they were pretty much out of school by the time they reached superstardom. I, on the other hand, listen to tons of new music, but if you asked me to name a random song on the radio, I probably wouldn't be able to name the artist primarily because I don't give a shit about the kind of music they play on the radio. I don't think new radio music is any better or worse than old radio music. It's always been corporate-driven pablum, autotune or not. As for autotune itself, it can be effective when used appropriately as a texture, and not necessarily as something to pitch-correct a bad singer.
