There's an element of this even within the community of a single language, too. E.g., Apple's been doing Swift talks at WWDC where they sort of introduce their blow-your-mind-paradigm-of-the-year: "Protocol Oriented Programming" was two years ago; "Embrace Algorithms (subtitle: delete your for loops)" was this year.

It concerns me because these are such lush, ripe targets for cargoculting. The behavior in this article is problematic exactly because of the "Apple says we must not use inheritance for anything! I can just use a protocol extension; that's totally not inheritance" mindset.
