Oh, I don't think its a hoax! Its certainly a hardware design issue that must to be fixed. But the data we have (and its not much, a admittedly) seems to suggest that its not quite as widespread as some might suggest. It is interesting thought that some people appear to be plagued by it more than others. Maybe typing baits play a big role in manifesting the inherent flaws?
I can't sat that I agree with this statement. The CPUs in these new machines are still best in class and GPUs are absolutely in line with what they were offering in the past (and they have rather adequate computer performance, all things considered). Its not like they have reduced the performance or built in some artificial limitations to achieve the thinness, actually, its more of the other way around since the newer machines have much better cooling system despite being thinner.
Yes, RAM limit might be an issue for some users, but there is a real problem with an increasing power draw. While RAM is getting progressively more power efficient, the increased need for it completely nullifies any of these savings. Back in the day, where 4GB was maximum you could get anyway, this wasn't a problem. When you start putting 16GB or even 32GB into your laptop, it definitely becomes a problem — since it is more or less permanent constant power draw which can make a very substantial portion of overall idle power consumption (30% or more).
Bottomline is that I don't think that Apple's decision to withhold 32GB configs so far is an indication of them valuing performance less. Its simply due to them operating within certain design envelope. Until not long ago, they could easily offer maximal or close to maximal amount of RAM within their designs since there was no reason not to. High power requirements of 32GB DDR4 makes is much more tricky to accommodate it though and would require to change the laptop's overall formula (in particular, make sacrifices to both battery life and portability). By the way, they've been consistently using low-voltage RAM fro some time now, at least since 2012 and possibly earlier.
In the end, its a rather unfortunate that Intel still does not support latest RAM standards in their CPUs and this of course puts Apple and other laptop makers in a difficult situation.
Lets wait and see what happens at WWDC though. Its possible that they might release a DDR4 config, who knows.
