Actually for this to be exploited someone would have to sit in range of your wi-fi for hours, patiently waiting to obtain the password. It can take more than 8 hours.
Then he can log into your system and find out what you posted to Facebook. This is big news for huge targets with lots of money. It's less than nothing for the rest of us.
Why would a criminal cyber-genius spend thousands for the equipment to sit in your driveway for eight hours sniffing your logon credentials for no gain? Why would they pick your driveway of the 50 million driveways in the United States alone?
This is only a concern for places crooks are absolutely positive there is money to be had. In that case there are dozens of less risky things than snatching packets whilst physically waiting to be apprehended with hacking tools in their car.
These security wonks have stopped thinking. Crooks want a safe and easy sting. They aren't going to put their butts on the line in your driveway to get your Amazon password, or even your bank password. Too little upside with too much downside.
If they do it in their underwear from the safety of their bunker in Turkmenistan there's no risk. They don't have to put their bodies in peril for six or eight hours waiting to be arrested in your driveway. And they don't need your wi-fi passwords!
This may not be fake news, but it IS fake danger.
