Maybe true for old machines, but definitely not true for newish models.
Not even for machines being sold with Linux preinstalled.
My Linux Dell XPS from ~5 years ago required me to buy and install a different radio because the Broadcom one didn't actually work with latest Ubuntu (at that time).
The next XPS I got mostly worked, but had lots of audio issues.
The Inspiron was horrible. Touchscreen fails, audio fails, radio fails, sleep fails.
My custom Ryzen 3900X workstation has ongoing issues with sound and sleep (yes, latest kernel, latest drivers, latest LTS OS).
My most recent laptop purchase from earlier this year either had no wifi in Ubuntu or no Bluetooth in Fedora. I was able to force Fedora to work after a week of messing with it. Still have intermittent sleep and audio issues.
FWIW, I've been running Linux in various roles since the late 90's, so not a noob and definitely not complaining.
It's free, it's open source, package management is awesome. The command line is irreplaceable.
I use Linux on the daily and deeply appreciate all the incredibly hard and thankless work that so many people put into it.
That said, Linux still does not have anything close to the level of polish that MacOS delivers and it definitely doesn't get out of the way to the extent that it can be called boring.
YMMV
I used an iMac running Yosemite that year and could reliably get the iMac to hard reboot by launching a Xubuntu VM in VirtualBox.
It kinda made me lose all hope for our industry as Apple is usually hailed as the epitome of quality and yet it still was garbage.
