Even if every of the 163,000 Microsoft employee got a company sponsored phone, that's still pretty much 2 orders of magnitude below the Lumia 520 sales figure alone.
Anecdotal of course, but my code is no longer there. My profile still exists because I want to open issues with the tools I'm using and what not. And every once in a while, I stumble upon a project with a big disclaimer that the main repo is now on GitLab.
I moved the past 3 companies I work with from GitHub to self-hosted gitlab after the Microsoft purchase.
When Microsoft bought GitHub, all of the "Developer Evangelist" / "Open Source" evangelist crowd made all of those noise about how "Microsoft is great for our community! They ARE an open source company! Everything is wine and roses!"
Google's erratic roadmap, less than stellar enterprise support, and shady privacy practices from their ad tech side just drive me away
