The frontier companies' models are not supposedly aligned. They routinely make the news for being misaligned. This goes double if you're arguing with doomers, who believe that alignment is a very hard and unsolved problem (and generally do not support these companies' approaches). The alignment they do have does not seem to be biased towards the companies that created them (yet), as far as I'm aware- GPT will write a scathing critique of OpenAI if asked, but it's possible there's some more subtle biases you're aware of?
