The message is good but the name makes no sense, and is almost the opposite of what’s described. In a traditional web app, the client has zero data, or just some cache. But in a "zero data app", in the way they mean it, the app has all the data, so certainly not "zero".
Go explain the concept to someone unfamiliar with it with a nonsensical name like this.
> It's zero data from the perspective of large tech entities.
I understand that, and in fact most developers do. However if they invent a new term, it should be something that makes sense to everybody (not just developers or large tech entities), or at least that doesn't require a complicated explanation to define it.
It's nothing new either, the trend for self hosting and offline first apps have been going on for a while. In my opinion they failed at finding a good term that encompasses all this.
