This is actually a marketing approach.
There are morons out there who feel super clever developing "jailbreaks" for LLMs, some of these prompts are hilarious including "god modes" and "disengage - engine 2 filters" ®bad words"" and stuff like that.
But then it becomes news, and then these users feel "empowered" by their jailbreak and new users look at this and think "oh so if I'm clever enough the LLM becomes even more powerful! I'm clever, so I'm going to try it!" which is ultimately what OpenAI wants.
You can't "bypass the system prompt" because that's not how it works. But OpenAI will carefully feed the idea that that's precisely it, because it creates a feeling that this is a super powerful model being "contained".
Again, it's marketing. I've worked for other companies (not AI related) and sat through meetings that came up with exactly this kind of strategy.
