There's a difference between "let's not start a port of Y at all" and "start degrading experience on an existing port of Z." (See? "MS is completely pro-Linux (where completely excludes anything that contradicts this, leading to a nice circular definition)" - that's as no-true-scotsman as you can get)
You are very clearly grabbing at straws here. This isn't some nefarious tinfoil hat plot. I honestly suspect their focus is truly being spent elsewhere.
