Nah. Microsoft bought Github among doing other things (WSL, becoming top member of the Linux Foundation etc.) because they want to replace GNU/Linux with their MS/Linux which could be mostly Open Source and mostly free, but I'm sure will be engineered in a way that gives Microsoft full control of it. There is no need to put Linux developers out of business when Linux developers themselves already use a MS dev system (VSCode) on a MS platform (WSL). Just wait for the day applications will start to nag users with "For best user experience, this Linux application should be run under WSL".
