I went on Facebook (I know I know I know) and they are selling tinfoil hats.

The "Wavestopper" costs $88 Free Shipping!

(I checked. It is not an April Fools joke. Selling to people with "brain fog" feels a little predatory to me.)

Do you think the people selling this are laughing at their customers or are they into it?

It's like a damn joke.

Around 25 years ago, there was a not-very-serious paper from MIT that pointed out that tinfoil hats are basically parabolic reflectors and so, rather than keeping out rays, they will focus them on the brain.

Possibly worth sharing with people who might buy this nonsense.

@david_chisnall @futurebird Well that's just the kind of thing Big 5G would say
