Nostr developers do care and do work hard, putting in a lot of time, effort, and their lives into their applications and projects. For the most part, these applications are being built by small teams of one person or just a couple people in their spare time. It's very different from traditional software applications that we use every day.

Do issues exist with most applications? Yes.

Are developers aware of said issues? Also yes.

Do they have infinite man hours, time, and budgets like large tech companies? No. No, they do not.

Do they still work on improving their applications? Yes. Yes, they do.

Have faith. No developer says hey I want to build a shit application today and piss people off.
