Meanwhile on Windows I am not exaggerating when I say that every computer I have owned and every peripheral device I have ever used has had serious issues. Wireless headphones randomly disconnect, microphones require frequent unplug-replug cycles, rebooting is often required, reinstalling is common. Mice and keyboards have weird compatibility issues with software drivers. This experience is shared with most people I know that I have discussed it with. People are just used to it.
Maybe it isn't Linux that is the problem. Maybe the problem is that consumer hardware is designed and built on the cheap and is not designed to last, and they get away with it because most people (1) have no idea it could be so much better and (2) have no insight into these issues before buying because they are rarely covered in reviews.
For some reason when this happens on Windows, the hardware is to blame, but when it happens on Linux, Linux is to blame.
Then, of course, I was also curious whether their reasoning was grounded, so I manually enabled acceleration and re-run the test - and found out that both Chrome and Firefox will inevitably crash in 2-3 hours of active browsing with it enabled, so they disable it for a reason.
As far as "maybe Linux isn't the problem" - you're broadly correct that it's really an issue of hardware quality and/or lack of good first party drivers. But from the end user perspective, if you can't reliably use Linux with popular off-the-shelf hardware, it's not really "ready for the desktop", regardless of where the blame lies. I've been a Linux user for 25 years now, with about a decade of using it as a primary desktop OS, and this exact excuse has been around for as long as I remember (I've used it myself plenty of times way back!). And yet, here we are.
