So you are assuming that if someone posts something negative, it is to start a war? What if the said person goes on and posts in other topics? Will his first posts still be classified as "warmongering" in your book?
Also, is there an unsaid rule that every new member's post should be something positive about Apple else it will be classified as "warmongering"?
So? When the buyer bought it, presumably he checked out the laptop. Found everything OK to his satisfaction. Paid money and took it home. How different is it from what Apple is doing today (or even, what it has been doing) ? Today, you walk into a store, check out the laptop, everything is ok then...at that point in time, you buy it. Sometime later, keyboard fails. If it is out of warranty, Apple will charge you a bomb to fix it...even though the design, IMHO, is flawed.
A better example was the GPU fiasco which I am not going to detail here (it has already been done countless times in these forums). Apple continued to sell these defective machines and refused to acknowledge the faults until a multiple class action lawsuits made them honest. Apple does this all the time!
And I should read your previous posts to understand your last post? I respond to most people here on the basis of what they just said. I do not go about digging their post history, building an identity of the person, and then choosing to respond.

Nothing personal mate. Just grumpy this morning.
Personally, I have lost 2 MBPs to GPU failures. Refunded repair costs by Apple post lawsuit. Tried out the 2016 model for work and returned it (thanks to the members of this forum). At that point, my teammates said I was paranoid. I have long left the company but I heard they no longer offer the 2016/2017 models for work. The dropdown only lists the 2015 model (which Apple still sells by the way).
