Companies only need to censor a model that's available to the public. They can do whatever they want internally.

I also think you're vastly understating the size of these language models. Even if they don't grow in size, we're still many many years away from them being runnable even at the hobbyist level. Very few people can afford $20k+ in GPU hardware. And that's just to run the thing. Training it costs millions. There's a massive difference between ChatGPT and StableDiffusion regarding scale.
