Well, they're actually sort of trapped, now, as they're sitting on a gigantic money bag and they are legally obligated to spend it, according to the principles defined by their nonprofit.

What they could do, is disintermediate the spending of the money, more, so that users have more direct say in where the funding goes and devs don't have to become de defacto employees, in order to receive foundation monies.

#Geyserfund does this with contribution amplification, where individuals are encouraged to contribute and they top-up the most popular projects.

We had the idea of arranging a Geyserfund #zapathon, with OpenSats contributing x-amount to the amplification effort, but the idea seems to have gone nowhere.

One of the things you can see on the Geyserfund page for Nostr projects is the higher heterogenity of the projects. The users don't only want funding going to devs. They find a lot of value in stuff like marketing, merchandise, documentation, meetups, etc. Nostr is a whole ecosystem, not merely a software project.
