Would you mind listing the Google Cloud Platform services that have been "taken away"? I'm honestly curious to know if the decision of shutting down services such as Reader impacts your perception towards Google's Cloud offerings.
Just because one hasn't been taken away yet doesn't mean it won't happen. Obviously Google has a bad track record regarding product lifetime and it's going to take some extra special care to win many people back.
I was just explaining to a colleague the best ways to get acces to shell utilities like awk/sed, as a Windows user. In the balance of ease of setup vs functionality I had recommended the git bash application. This looks even better (for 2016).
In addition to all the other stuff, there is also MSYS2 [1] which includes pacman (the package manager from Arch ported over) and a decent sized package repository.
It says: "The virtual machine instance that backs your Cloud Shell session is not permanently allocated to a Cloud Shell session and terminates if the session is inactive for an hour. After the instance is terminated, any modifications that you made to it outside your $HOME are lost."
