“Objur” has a double-meaning here. First, it is a transliteration of an armenian word (աղբյուր) that refers to a fountain, spring, or other source of water—fitting for a product that helps with OS hydration. Second, it is related to the English word “objure,” which means to urge or bind someone under an oath—again, fitting for a tool that urges user updates while having them promise (swear?) that they will comply with appropriate updates.
