I worked on an app team, PowerPoint. After Balmer left, policies changed such that any new office app features had to ship on both windows and Mac at the same time. (Or least try to)

So I think that definitely helped and allowed people to request macs as thier laptops. For azure, I’m not sure…

Yup they do, I worked there. Had 2 macs and an iPhone for development. Many employees use Mac laptops over surfaces as well
