Exactly. These days there are several vendors preinstalling GNU/Linux on their machines where everything works, and it's really not hard to find machines where it's not preinstalled but where everything works anyway. These memes are memes because it's also not hard to stumble upon a machine where it doesn't if you just take a random one, but that's hardly surprising - just take a look at how much effort it takes to run Windows on Steam Deck and have everything work well there. Someone needs to put that effort first when the vendor does not. I love those "I had issues so everyone else must have had them too" takes. I can give some anecdata too: the last integration issue I had on machines I've been running GNU/Linux on was a non-working SoundBlaster Audigy card somewhere around 2006 - and I've been mostly using laptops afterwards, some of them being from vendors that didn't provide any GNU/Linux support at all. (that sound card eventually gained support in ALSA, by the way)
