I recommend the podcast greatly.
But perhaps we need a simpler approach - a funded "journalism" archive where the tech firms can shift the posts to online storage (ie not delete it) but section it off for later analysis.
Seems the only likely compromise.
I meant to say the Internet Archive can be used as the 'funded "journalism" archive' that GP mentioned.
I can imagine a way of referencing these redacted images that facebooks just puts up a big red sign and a warning - but that still allows people to find it and it acts as a full web citizen.
