Could you imagine that to become a reality in the past?
I could, and to be honest I liked Microsoft better when they were openly antagonistic toward Linux and FOSS in general. WSL, GitHub, etc. smells too much of the old “Embrace, Extend, Extinguish” strategy for my liking. People say Microsoft has changed, but I don’t think the corporation has changed as dramatically as people claim.
I just think Microsoft’s senior management has learned subtlety.
I don’t trust MS, I don’t like MS, and I only use their products (free or paid) when I’m getting paid to put up with them.
