>Imagine taking someone who is so passionate about UX that they made a career out of it, making them use their worst nightmare as their daily driver, and then giving them zero institutional power to fix any of it because of the n-dev years problem.

1 Those people are paid, as a dev I am paid to use JS and PHP , I am not crying here because poor me I can't use my favorite language Prolog or Lisp so why a designer should cry if he does not work on his preferred shit. They can use Linux or OSX at home.

2 this designers call themselves UX people. This means they don't work with images of GUIs , they should in fact use the product as an user would use. Ex: you are a UX dev for the Word product but you always use Word with a document of 1 page length, then you would never feel the pains your users that have documents of 50+ , 100+ pages feel. As a dev and UX designers you should use the product you create.

3 If you are a designer in the sense you create logos and icons then probably is fine you don't use the product, though if you are a web designer and really love fucking with fonts and fonts color PLEASE borrow a regular laptop from a friend and check your website in it, your cool fonts might look different on a different machine and maybe you also will be reminded that not everyone has high definition laptop screens.
