No - it was the language that I said was transphobic, not the author. Given that there were two different word choices (“transsexual” and “perceived gender”) that reinforced each other, it seems more likely than not that they reflected the mindset of the author, but not having looked further for their other writings I was not sure. That’s why I said " transphobic language" and not “transphobic author”.
The context is that the original version of the keyboard didn’t have the q a and z keys on the right side at all. QMK and similar keyboard firmwares have features that let a key send one code when tapped and a different code when held or pressed, and even another when double tapped.
The keyboard designer made themself a keyboard where ESC, Tab, and Shift keys were set up to send q, a, and z on a quick tap, and got so many comments on multiple videos asking how they could possibly use a keyboard missing three letters that they made another keyboard with the three cockeyed keys added on the right as a joke.
