That’s not what happened at all imho.
What killed digg realistically is that it had less control than Reddit and because Kevin Rose blocked posts about the DVD encryption codes and people over reacted to that block. For days digg was full of people simply reposting them (as Digg was worried about getting sued which was fair enough)
Didn’t really have anything to do with politics.
Don’t forget, this was back in the day of fat people hate and Reddit hosting child porn. Reddit administration was never great
Digg admins were actually ok and I never had an issue with them
I’d say the ones who have been saying it’s not real should be the first to become soylent green
