This is theft that gets around a copyright loophole. Don’t steal recipes.
Where is the limit ?
For me it's just a web browser optimized for recipe websites. It's basic scrapping. Google does it, why can't I do it ?
Are "reader mode" browser extensions theft ? Are ad blockers theft ?
Is using Lynx as a web browser theft ?
If your business depends on your content never being scraped, you are screwed.
