These are my observations running a hackerspace in bitcoin.

I see two main issues: Nostr is a niche within a niche and Bitcoiners do not like to pay for things.

So you have to be creative and charge significant amount more for services rendered.

The last thing is most Bitcoin companies and Nostr projects need help just punching through the noise.

At PlebLab everyone to my knowlege is + on arr vs opex minus a few companies. I suspect it has more to do with general support pleblab provides them.
