Because windows has WSL? You have a 1st party directly integrated Linux already. My work laptop is a MacBook Pro and we use Docker Desktop, but for my personal work I use a desktop and run WSL/Ubuntu.

All my GUI stuff and text editors are on the windows side and the actual software all runs in docker in the Ubuntu subsystem.

Docker and WSL are complementary, and often used together. Otherwise why would anyone on Linux use Docker acc to you?
