I agree with you. The reason why we still link it to Bloomberg is because of the vision we have, not the current state of the project. Kind of similar to a self-driving startup mentioning that they will become a Tesla - It's not true, but you get the idea and concept.
I made the repo open-source first at the end of February, given that we are only 3 devs (2 adding features and 1 dev ops) all with full-time jobs, there's only so much we can get our hands on.
I don't have access to Bloomberg Terminal. But I'm pretty confident that there are features that we've got that Bloomberg doesn't. E.g. we have a screener for stocks that can be specified by our user base and made available by everyone (https://github.com/GamestonkTerminal/GamestonkTerminal/tree/...). This is what having an open-source project can bring, combining collective knowledge of the community.
