Vscode is a text editor/IDE, it has bajillion alternatives, again unless MS doesn't allow code not written in Vscode to GitHub, which is a suicide anyway. There is Bitbucket or Gitlab to fork to.
WSL, is awesome, because Linux is not game friendly, yeah yeah proton blah blah. I own a steam deck I know how it works and for a casual user Linux gaming just isn't there unless you want to tinker a lot. Then there are products like Photoshop replacements for which Linux is sub par, no GIMP is not alternative, it's entirely different. But nothing is stopping other users to switch to Linux unless edge/windows 11 blackholes insert_your_favorite_linux.com. WSL just clicked for a reason.
MS as a company will fight for market share, no company after a certain size is moral, it's "free market" as US defines it. Change laws not companies. Regulate not ask nice. Feels like EU knows this and at least tries to twist the arms of companies where as in US it's seen as infringement of freedom.
Ms gobbling up dev community is fear mongering towards the wrong entity.
