>>"sunlight is the best disinfectant" is completely and utterly wrong.
Certainly for some types of infectant such as weapons-grade dezinformatsiya...
Or at least, to achieve disinfection, that sunlight needs to be applied at intensities found on the surface of the sun vs at the surface of the earth.
To me, it's the difference between default private and default public. On both platforms you can curate your content, and arguably the worst content festers on Facebook because it is so hidden from the public eye, but it also means it doesn't have to find its way to you.
Facebook as a company has had much more problematic behavior, I'd agree with that one for sure.
But if there's anything we've learned from the past decade, it's the old axiom "sunlight is the best disinfectant" is completely and utterly wrong.
