As soon as they came out with scale, I knew core was going to be cut off when scale got good enough. There are just more possibilities with what you can do with Linux.

At the end of the day, they gotta eat too and having one base system instead of two is the way they need to do it. The features are growing much faster on scale than they ever were on core in my opinion.
