It’s a least-common denominator effect.

I.e., most people don’t care.

Local-first is optimal for creative and productivity apps. (Conversely, non-local-first are terrible for these.)

But most people are neither creative nor optimally productive (or care to be).

> most people don’t care.

it's not that they "don't care", but that they dont know this is an issue that needs to be cared about. Like privacy, they didnt think they need it until they do, but by then it's too late.
