So let's assume I am indexing nostr notes for a search project. Can I still comply by e.g. open sourcing my code, maybe providing a NIP-50 like endpoint? What else can/should I do to atone? (Or should I be morally prohibited to index notes "centrally"?)
Discussion
It should not be news to you that anything uploaded to the public web is fair game, technically speaking.
There are no good answers, only better questions to ask ourselves:
"Is the likely effect/outcome of my project more likely to ultimately help or hinder the movement towards freedom-orientated tech?"
"Have I thoroughly and deeply considered the ways in which bad actors might leverage my tech towards undesirable ends?"
"If everyone knew what I was doing, would that bother me? If so, why?"
