I just think Element14. I agree with you, it is so generic as to be meaningless. Signal makes sense. iMessage & Facetime do what they say. Whatsapp at least sounds like a fun app even if the name is meaningless.
I think WhatsApp is a play on "What's Up" which actually makes a lot of sense given that's pretty much the point of a lot of casual conversation haha
I think of Element the skateboarding company
Same here.
How about another very generic and common word, “Apple.”
Except they were originally "Apple Computers" until they slowly gained enough recognition to rebrand to "Apple," plus that was in 1984, there wasn't an oversatuated market of other computer brands also called "Apple," unlike "Element" which has tons of existing tech-related and non–tech-related overlap and is generic on top of it.
