My favourite was the Azure CTO complaining that Git was unintuitive, clunky and difficult to use

Sounds like he’s describing Windows phone.

Feel like I have to defend windows phone here, I liked it! Although I swore off the platform after the hardware I bought wasn’t eligible for the windows phone 8 upgrade even though the hardware was less than two years old. They punished early adopters

Yeah Windows Phone's first releases were decent. I have developed apps for Windows actually using Window's UWP framework but there weren't enough users on their platform sadly.

Isn’t it?

Ironically, the GitHub Desktop Windows app is quite nice.

Yes. But the point is compared to Azure in places the statement was very much the pot commenting on the kettles sooty arse. And git makes no particular pretence to be particularly friendly, just that it does a particular job efficiently.
