This is true for almost any random laptop, and has been since forever.
Its obvious the M1 and its successors have a chance of becoming a well known constant since its a SoC, and not a collection of random components from many vendors (that might or might not have good inline-Linux driver). Intel Macs, other laptops have had different hardware components even for the same model over its lifetime.
Not this old trope again.
I haven’t had WiFi and sleep issues with Linux for at least a decade (I don’t use Bluetooth on laptops so can’t comment there). And I do use random laptops, including MBPs.
People seem to hold on to the same old arguments about Linux that were true back when XP was released but things have unsurprisingly moved on since then.
For sone random hp or whatever crappy netbook maybe yes, but you can’t compare a MacBook to that. There are good laptops that don’t have those problems, I haven’t run into any issues with my Thinkpad.
