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
Can you use OPNsense for general things or is it tailored to one specific usecase?
You can install packages on it, I’d say it’s tailored to be a firewall/router
