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.
