My 20 month old (i.e. out of warranty and with no Applecare policy) iphone 6+ started showing the symptoms a week and a half ago. The "Genius" at the Apple Store immediately recognised the symptoms and processed a free replacement (refurbished) phone without any prompting or negotiation on my part.
So while it's true that they are staying very quiet about it in public, it does seem that knowledge of the problem and a free replacement policy has been communicated within the company.
There was recently a lawsuit in the Netherlands where someone sued Apple after receiving a refurbished phone after replacement under warranty [1]. She won the case:

The judge based his verdict on a verdict of the European Court of Justice [2], so it's likely that the outcome would be the same in other EU countries.
[1] 20 months would still fall under warranty in the EU.

On refurb, many (but absolutely not all point of contact for chips to PCB) are tested, but require lower tolerances
Perhaps a timely reminder than the plural of anecdote is not data.
Most people I know who got RROD ended up just throwing their 360 out.
Also never had an issue with the Oneplus, it has taken a battering and I have successfully changed the screen 3 times, survived a full submersion while turned on and numerous drops. It is currently missing the on\off button due to my carelessness but it is still going strong.
