I just don't understand why people seem so upset about these new companies being GPT wrappers.

A lot are just close to vaporware. It also takes advantage of people more than most business models.

If your business is just adding a system prompt and trying to keep users from figuring out you could just do this with ChatGPT, I can't say I'm a fan. Not a hater... but not a fan.

If you have more functionality with actions, events and context, that's fine.
