I think it's because you're old. Taylor Swift is still producing stuff, Chapel Roan, Billie Eyelash and Sabrina Carpenter are apparently popular (can't name of any of their crap).
I think largely it's because it's mass produced carefully marketed crap that's meant to fit carefully crafted anti-conservative sentiments. Your taste in music also feeds largely into this, where it's 2020s pop that's winning rather than classic/punk rock that was popular in the early 00s.
This seems to be pretty global even over the Christian side. Skillet is still producing banger after banger, but a lot of other bands have stalled, I guess because there's less demand for the genre. Worship music in the mid-00s was built around classic-rock tones but now is mostly synth pop.
We probably have to wait for the cycle to come back around to punk rock and the world can heal.
