I wonder if id Software will continue the tradition of open sourcing stuff under Bethesda.
I do not expect to see Office for Linux, a proper release of Minecraft for Linux with feature parity with Windows, etc. I also do not expect to see Xamarin development on Linux. I do not expect to see a proper release of Skype on Linux either. The only exception to this trend is VS code.
Edge for Linux doesn't bring anything new to the Linux desktop. There are already plenty of browsers such as Firefox and Chrome and others.
And I am deeply thankful that Microsoft won't buy Discord. Discord works very well on Linux and I hope it stays that way.
