I think the issue with centralized communication tools is that we haven't figured out the "shame" thing yet. Or, perhaps, it isn't even possible to scale up shaming. There's a lot of evidence that scaling up shaming simply results in its weaponization (the internet doesn't do nuance...). Watching Roseanne on Joe Rogan this week was simply heart-breaking. The speed with which her entire career and body of work was tossed in the garbage really makes me think that it isn't possible.
