I've recently been considering making my own open source nutrition app, (since every single one I've looked at seems to either violate my privacy&security, or is designed/works very poorly), but the available "open" nutrition info databases for bootstrapping have seemed poor.
So I looked at the license of this database, and the idea of making it "open" is good and maybe appropriate. But the attribution requirements to promote this other, commercial, product are a little annoying. And could also be a little confusing in app store listings.
> Attribution Requirements: If you display or use any data from this dataset, you must provide clear attribution to "OpenNutrition" with a link to https://www.opennutrition.app in:
> * Every interface where data is displayed
> * Application store listings
> * Your website
> * Legal/about sections
Additionally, I've soured on single companies that call themselves "open". "Open" has a few-decades history in computers, as everyone realized the dangers and costs of proprietary lock-ins, and so created concepts such as "open systems" and "open standards". Appropriating the "open" term for a single company, for something more proprietary than open (like the very proprietary OpenAI that's mentioned many times in https://www.opennutrition.app/about ), rubs a bit the wrong way.
