How does this benefit the Linux community even more? Microsofts move to include shells and a kernel compatible with Unix may end up being one of the most damaging things to Linux in a long time.

All of the casual users that don't care about open source will just give in and use Windows as their OS when they hit a driver snag or something since they still get the userspace tools they like.

Which is what "casual users" have been doing with macOS for a while now: getting some of the BSD userspace tools they like in a friendlier overall OS package.

If anything Microsoft is providing a way to encourage Windows users that would never touch a BSD or Linux userspace tool to give it a try. That's a possible way to bring new users to Linux: teach them how to do things with Linux userspace tools and encourage them to dive deeper until they can do everything they want with Linux userspace tools and then maybe encourage them to switch.

If anything, Microsoft has given the Linux community the keys to possibly embrace some "casual users" that otherwise never would have explored Linux.
