I wanted to ask the community what to do.You should comply and be grateful that we live in a world where you get a warning first before penalties are applied for miscomprehension of laws and of rights in general, not even just copyrights, because not everyone has been historically lucky enough to get a polite warning first.
> In summary, a trademark lawyer is sending me threatening emails
First, that's not threatening, and second, the message specifically discusses copyrights not trademarks.
> No one viewed these except me. Github's traffic stats show 2 viewers total.
That's just not relevant. The phrase you want to investigate here is "making available". Using the phrase in a sentence, one could say something like "I made naked photos of you available to your coworkers, which was incredibly disrespectful of me, even if only illegal on copyright grounds, because you want to be able to control when, where, and to whom those photos are shared, and you only shared them with me on the condition that I wouldn't then go and make them available to other people without your consent, consent which a respectful and respectable individual would get."

> It feels wrong that a billion-dollar startup is threatening the very developers they're counting on to make them money, so I didn't necessarily want to encourage this behavior.
I'm going to give you the best and most difficult to follow advice that you will ever receive: You do not get to make that decision for them. You only get to make decisions for yourself.
> Ultimately, I think I'm willing to make a stand over this
What stand are we talking about here? The copyright case seems very clear cut in their favor. In at least the legal sense, you don't have a leg to stand on.
> but ideally I'd like to not be dragged into court over some 3 month old API docs
Good. That's exactly the right feeling.
> What are my options?
Stop illegally infringing their exclusive right to control how documents that they authored are made available to the public? Stop developing for proprietary platforms that wield copyright like this?
> The ideal outcome would be that Magic Leap changes its behavior
True fact: You don't get to decide for someone else how they exercise their legal rights. If you don't agree with copyright, don't support organizations that leverage it. But be prepared to either lose, comply, or not get caught in the first place whenever you break whatever punishable laws are in place wherever you happen to be.
