CM 12.1 including Google Play Services and Google Play Store: WHY?

I have just noticed that CM 12.1 nightlies are including the Google Play Services and Google Play Store stuff by default.
I was willing to install a google-free ROM and CM was my choice. Now that cannot be any more.
1. Wasn't that forbidden by Google itself?
2. How can I remove that, as I really really need a google-free installation?
3. I think I have missed some important announcement, any link?

Thanks in advance.
