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.
The linked article provides many examples where security techniques lag far behind Windows. Vulnerability isn’t as simple as being ‘more vulnerable’ or ‘less vulnerable’, it’s a complex concept, and both GNU/Linux and Windows have design decisions which make each better than the other in various ways. We need to understand security in a more nuanced way than “x is better than y” if we actually want to protect ourselves from threats.
A Linux installation can be set to run root with no password or prompt. A Linux user can choose to never update their software - one could argue that Windows forced OS updates are an improvement here. The argument that the typical user has more technical understanding is a weak defense (as in, we really really really should not rely on that) and also irrelevant when we’re talking about Linux gaining a wider audience.
