I believe all of them are doing unethical research, especially facial recognition. Notice the public backpedaling this week from all the big tech companies on this too. By directing their cash through OpenAI they can avoid whatever fallout comes from unleashing things like GPT3 on the world.
The most straightforward use case for GPT3 is generating fake but believable text. AKA spam. That's what it was designed to do. If you think fake news is a problem now, wait till someone is generating a dozen fake but believable news articles per minute by seeding GPT3 with a few words and hitting a button.
Its a conspiracy theory with some circumstantial evidence. We will probably never know either way, because who would admit to it if it was true.
