I had some issues with my AMD X13 when getting it new - but they weren't show-stopping, just annoying, and they got ironed out over the next 6 months.
I'm confused where you got that idea. T2 chips changed a lot. The most recent Intel MBPs have a different wifi with a known-broken firmware for Linux. The sound handling has also changed and hasn't been reverse engineered yet since 2019. And that's before we even get to changing the entire architecture to M1. How is that less changes than lenovo?
Notably the Asahi project got M2 laptops up to parity with the M1 family in ~48 hours of dev work. No doubt this won't always be the case (there's bound to be major hardware revisions at some point) but at the moment this is quite promising looking towards the future.
