I can offer no ELI5 but here's the context

Shouldn't'a been bitin' ma horsey, boi
A Riemannian manifold isn't necessarily non-Euclidean, it's just a smooth manifold with a Riemannian metric, which is just sort of a way of defining local geometry in a coherent way. Namely it's a smooth family of inner products on the tangent spaces at each point, where an inner product on the tangent space is sort of a way of comparing any two directions at a point and the smoothly varying part means that for sufficiently close points, the comparison function on their respective tangent spaces is similar.
Anyway, like "manifold" is a formalism intended to capture the idea of a "shape or space," a "Riemannian manifold" is just "a shape or space we can do geometry on."
Feeling the pain for a bit will quickly make you comfortable with the numbness
IT WAS TWENTY YEARS AGO TODAY
People are using LLMs to diagnose disease, write prescriptions, deny health care claims, deny loans and grants, write scientific papers, review scientific papers, draft engineering and architectural documents, and talk to their loved ones
Despair
It's possible that whatever prompt enhancement and processing happens around the LLM part of the application addresses this somewhat.
I don't support the change. That's not my point. My point is that if we're going to argue the dev being threatened isn't a victim because he's actively harming privacy, we should be aware that the changes he proposed are not actually harming privacy at all.
As I said, I also object, but you have to realize you're literally just doing the slippery slope meme unironically. The part that makes it a fallacy is the unjustified assertion that more egregious changes are the inevitable result of the first one, except the first one is materially harmless and in line with existing PII fields in userdb. It's completely reasonable to expect systemd to go no further than it already has.
What?
No, it literally just can't violate your privacy in any way. You have complete control over what, if anything, is placed in that field. No information about you can be gained or disclosed by virtue of the systemd change alone. You can think it's a bad change because it signals intent to follow a trend of supporting privacy-invading age verification, but you can't say this specific change in itself is privacy-invading.
