No it abuses security vulnerabilities in 3rd party businesses who are using OpenAI. It doesn't get you access to OpenAI's api at OpenAI's expense. It gets you access at [vulnerable 3rd party]'s expense. Bankrupting someone using OpenAI doesn't seem to achieve much in the way of democratization of AI tools, sorry.
it's not bankrupting them, as the author is highly ethic (by using only "Big companies" open apis and remove the small one and the ones that ask from him to be removed).
But as for your comment, i see it rather as opportunity to make it only with Opt-in by the companies themselves.
That way it will actually make it even win-win situation for them for Marketing and Ads (with lower price).
Only stealing from people who haven't asked you nicely to stop doesn't scream "highly ethical" to me
Security researchers put a lot of emphasis on responsibly disclosing vulnerabilities. The maintainers of this project could have easily done the same, but they didn't
Of course! If this was opt-in then the only problem would be between OpenAI and the service providers to decide whether that's an allowable user of OpenAI's apis based on the terms of service and whatnot.
