The front page was changed to state this is not affiliated with other popular internet based gpt's in first few sentences. I get why people are cynical but the project really is trying to do the right thing.
Except this isn't coca cola. This is a term of art that is widely used in the industry and a number. OpenAI is welcome to rebrand on something that isn't so generic.
But we aren't actively trying that is why the frontpage was updated to respond to exactly this criticism. There is no active deception going on here. You don't like the name, that's fine, but it clearly states it isn't affiliated.
The website domain is still gpt4all.io, the project is still named "GPT4All Chat" and the GitHub project's title is "gpt4all-chat". Not sure how that is responding to the criticism that the project name is misleading. It's not that I don't like the name, is that it seems you're trying to make people believe the project is something it's not.
Yes, OpenAI's name is also misleading. When they moved from doing Open Source, Open research and being non-profit, they should have changed the name as it's no longer accurate.
