The news in the article is that CNCF spent good money to wipe out a copyleft license. They think history has shown a more permissive license without copyleft or a patent grab (just a patent notice) - namely ASLv2 - is a far superior choice and paid to get that in place. Their very recent explanation is well worth reading: https://www.cncf.io/blog/2017/02/01/cncf-recommends-aslv2

I'll explain what I mean by patent notice since those are my words, quick version: If you don't declare that you have patent rights affecting a portion of code you have contributed, you've given those patent rights.
