Clickbaity title on the original article, but I think this is the most important point to consider from it:
After getting to 1% in approximately 2011, it took about a decade to double that to 2%. The jump from 2% to 3% took just over two years, and 3% to 4% took less than a year.
Get the picture? The Linux desktop is growing, and it’s growing fast.
Is it any good
I only installed it once for fun in a VM but didn’t really use it. It’s different to Linux but you could get used to it. As far as I know however the hardware that it properly runs on is quite limited, mainly older stuff. So I wouldn’t recommend it as a daily driver but I would recommend to try it out.
I would definitely recommend OPNSense. The hardware support is quite good
