That's why monopoly is a bad thing. It allows manufacturer to pressure the vendor. The reason amd don't sells much in laptop market is extremely simple. Because you can't buy it. These vendors usually have far less version of amd laptop than intel one. And those are usually sells out quickly.
Every time I've tried it in the last 10 years, it's felt like I was teleported into the late 90s PC era - weird bugs in specific drivers that you can find lots of reports of for this specific model and no resolution, heat management that feels like someone in a basement strung things together in 5 minutes and never tested it again, strange failures in "plug and play" support for USB devices that work on every other machine flawlessly with the same cable and device, and don't get me started on Bluetooth. (My favorite ever might be the time that attempting to pair a specific pair of headphones to the laptop shut off every USB port, reproducibly, apparently because the BT adapter was connected over the USB M.2 pins to the root hub, and was crashing in firmware, so both Windows and Linux did the same style of dance of "try to reset it, once that fails, go up a level and turn off the complex to make sure other things keep working"...except up one level was the root.) (Though, to be fair to AMD, that was an Intel BT/wifi chip in an AMD laptop...)
I really want to like and recommend AMD mobile hardware, but every time I've tried it has been a shitshow without fail.
