The graphic "Internal structure of tech companies" comes to mind, given if true, would explain why the process/workflow is so different between the teams at Microsoft: https://i.imgur.com/WQiuIIB.png
Imagine the Copilot team has a KPI about usage, matching the company OKRs or whatever about making sure the world is using Microsoft's AI enough, so they have a mandate/leverage to get the other teams to use it regardless of if it's helping or not.
For example, if tomorrow my company announced that everyone was being switched to Windows, I would simply quit. I don’t care that WSL exists, overall it would be detrimental to my workday, and I have other options.
Personally i would also not particularly like it.
