Are you sure you read their announcement blog? You seem to believe that they didn't say what they spent an entire blog post saying.
Here it is again.
https://openai.com/blog/better-language-models/
They said
"Due to concerns about large language models being used to generate deceptive, biased, or abusive language at scale, we are only releasing a much smaller version of GPT-2 along with sampling code."
And in case it wasn't clear what they mean by "abusive language", they clarified:
"Today, malicious actors—some of which are political in nature—have already begun to target the shared online commons, using things like “robotic tools, fake accounts and dedicated teams to troll individuals with hateful commentary or smears that make them afraid to speak, or difficult to be heard or believed”"
"These findings, combined with earlier results on synthetic imagery, audio, and video, imply that technologies are reducing the cost of generating fake content and waging disinformation campaigns. The public at large will need to become more skeptical of text they find online."
Or summarised:
• We think people believe things they read online today.
• We think there are political "disinformation campaigns" being waged, by the sort of people who would use AI to wage them more effectively.
• We think GPT-2 would let them create "deceptive, biased or abusive language" automatically, and this is too dangerous to release because people aren't skeptical enough of what they read online.
• We think the entire population needs to change its behaviour for GPT-2 to be safe to release.
I think that directly supports my arguments. Their whole worldview assumes the population is naive, easily manipulated by text and more importantly the volume of it ... they also draw a bogus analogy to DeepFakes. It's bogus because nothing stops anyone writing words today that OpenAI staff might find "biased" or "deceptive", literally anyone can do that. But substituting a celebrities face onto porn would require very advanced video editing skills most people don't have: DeepFakes is a truly new capability, whereas GPT-2 is merely a capability of scale.
To believe GPT-2 changes anything you must believe the majority of people make up their minds on political issues based purely on volumes of anonymous online comments. Hence my argument.
