I think you missed to read that NOPE

Q: Is this Caffeine Update because of Company X or Y is doing Z?
A: Nope. I love competition in search and want lots of it, but this change has been in the works for months. I think the best way for Google to do well in search is to continue what we’ve done for the last decade or so: focus relentlessly on pushing our search quality forward. Nobody cares more about search than Google, and I don’t think we’ll ever stop trying to improve.

I think you also know about X, Y, Z
