There is no Hexus News coverage of Spectre 3 and Spectre 4, why?

News broke 2 days ago and it's another nasty (ish) one that affects all CPUs:
It's already mitigated but they are turned off by default so for security you have to turn them on. AMD is lightly impacted but Intel said themselves that they say a 2-8% degradation depending on tasks, on top of the existing degradation by the Meltdown/Spectre patches.It affects modern out-of-order execution processor cores from Intel, AMD, and Arm, as well as IBM's Power 8, Power 9, and System z CPUs. Bear in mind, Arm cores are used the world over in smartphones, tablets, and embedded electronics.
The fourth variant can be potentially exploited by script files running within a program – such as JavaScript on a webpage in a browser tab – to lift sensitive information out of other parts of the application – such as personal details from another tab.
I don't want to poke the lovely newswriters at Hexus, but a fake tweet gets a splashtop but critical security flaws are not?
