Yet the owners of nostr.build cared enough to make sure their servers couldn't be used for that purpose, from the get go, because they're aware of the ethical and legal ramifications of not caring. Their system may not be perfect, there may occasionally be an issue, I don't know, but at least they've done what they can.

Yes, they care.
I care about a lot of things that you don't but should.
There are an infinite number of things you should care about, but don't, just as there are for me.
If I was a developer and built a custom service like nostr.build I would care alot about that server.
They are right to care about their service.
If I had invested more than 30 seconds of setup time for my relay or if I ran it professionally or offered any kind of guarantees about it I would care. But for the 30 seconds of invested time, I don't have the time or inclination to care.
I care a lot about trying to convince you I don't care, however 😂
I forsee serious issues for people in the future if things don't change. I'll tell you why it's pissed me off too - because it was there, on my screen. Only for fractions of a second but that was too much. It won't be much of a legal defence to say 'yeah but I didn't know or care' if and when that day comes. Relay operators will be treated much the same as content hosting platforms. For the time being, the only relay I'll run is the one on my phone. Till such a time as the tools are there to prevent the bad stuff, or until there's some clear indication that efforts are being made, it simply isn't worth the risk of running a public relay.
