You are downvoted, but you are right. In Asia (esp India, Indonesia, Phillipines & China) but also in the EU, I see 'most developers' walking around with PC (Linux or Windows=>mostly Windows of course) laptops. I would say that by a very large margin 'most developers' on earth use Windows machines.
The most vocal and visible (and rich) ones have Macbook's though, i guess that's where the idea comes from.
I'm guessing some took issue with the possibly poorly phrased "our understanding [...] of what [...] 'developers' mean [differ]". It can be read as me dismissing people that use Macs as "not real developers", where my intent was to counteract the opposite: people dismissing others that might be using Windows as "not real developers" because otherwise they would be using Macs, which is circular logic that I have heard expressed in the past. And I say that as someone who has used Macs at work for the past decade.
It's actually from the 2020 survey in 2019 windows was at 47,5% and in 2018 at 49,9%. Unfortunately this metric apparently wasn't tracked in 2017 so we'll never be sure if they were above 50% back then.
So currently the majority of responding dev use a POSIX (mostly)-compliant operating system. That is actual food for thought.
