Yet, one of the main companies behind Linux is Microsoft and one of the main companies behind BSD is Apple. It's really hard not to have a negative outlook on both.
Apple is not behind BSD at all, using Darwin is not being behind BSD. Any of the the popular BSD distributions is not backed by Apple. Not to mention Microsoft needs linux, not the other way around. Microsoft is desperate to get linux developers on windows, using WSL. They had to rename Windows Azure to Microsoft Azure. Linux would not be affected at all if Microsoft stops contributing. Azure will be if it stops offering Linux VMs.
