The post didn’t ask for ethical requirements to be included in the advice.

Right… everything does have ethical requirements though. As soon as a member of a society does make something that impacts themselves and others it has ethical requirements. Some examples :

• voting (obviously)
• buying a Xmas (avoiding slave labor)
• selecting toilet paper (limiting pollution)
• buying a coffee (fair trade)
• paying an electricity bill (source of the energy)
• posting on Lemmy (avoiding centralization)

Everything, literally everything we do, has ethical requirements. We don’t have to say it because it’s implied.

Now… if you are genuinely curious about the topic I can only recommend en.wikipedia.org/wiki/Ethics_in_mathematics showing that even in the most abstract field, there are ALSO ethical requirements. Nobody can avoid that.
