It's not from some whack-a-doodle anti-PS4 source, but from current PS4 documentation.
Also, 2 of the 8 CPU cores are reserved for the OS.
(The Xbone reserves 3GB of memory as a hard limit, for comparison. It also reserves 2 CPU cores for the OS.)
Just goes to show that if you give a console a large memory, the vendor will figure out a way to bloat the OS up to ridiculous sizes.

The folks over at Digital Foundry cite "current PlayStation 4 documentation shown to Digital Foundry by a well-placed development source" in detailing the RAM breakdown. The numbers aren't set in stone, though. Digital Foundry reports that developers can take back as much as 1GB of "flexible memory" from the OS when it's available. However, taking back this memory isn't as simple as flipping a switch; it's complicated enough that only first-party games may be able to do it at first, according to the report.
