That's great and all, but I'm not sure what point you're trying to make. That there isn't a problem of malware/ransomware? Because there certainly is, and for most organizations the risk of malware/ransomware is much more significant than the fact that Windows gets some error reporting and usage statistics and such.

Microsoft is certainly doing their best to mitigate the negative consequences of the monoculture, but it remains a fact and an issue. Just like in biological systems, diversity in software is also critically important for the health of the population.

But soon I will have to go to the offices of the startup that I work for (I work remotely) and they all use Mac, and I am a bit worried if they start asking question about how I keep my computer secure. Anyone (not only parent author) can recommend something? A software to install or anything like that?
