You summed it up perfectly.only with context in colloquial speech, where we use words very imprecisely, that one could infer this: so I wouldn't even say this proves, philosophically, that one can derive an 'ought' from an 'is'. — Bob Ross
A command is not the same thing as a moral ought. An ought is something that we do "because it is in right" not because we are commanded to do it by another person.
I think the confusion, Sirius, may be that various metaethical debates, and the depiction of Hume's Guillotine, incorrectly depict them as "ought" vs. "is"s--but the english language has many examples of ought statements which aren't, in-themselves, moral statements.
Also, inferring "You should kill Tom" from "Today is Tom's last day on earth" is just an inference from colloquial speech: technically, one cannot logically nor coherently derive, all else being equal, the former from the latter. It is only with context in colloquial speech, where we use words very imprecisely, that one could infer this: so I wouldn't even say this proves, philosophically, that one can derive an 'ought' from an 'is'.
Perhaps if you specified exactly what "Ought" you are deriving I might be able to offer a more specific argument. If you are suggesting that "You should kill Tom" is an ought, I would respond that this is nothing more than an example of an illocutionary act (command by the boss) and that the perlocutionary effect consists of the hitman's response to the command. If this is your definition of the meaning of an "ought" then, logically, any time anyone tells us to do something and we accept, the conditions for normativity have been satisfied, which is absurd.
A poor child comes to you and spreads his hand saying, "I am starving" , you can derive the implication from his statement, "You should give me ( a poor child ) some money" . He is not just stating a fact, "I am starving" , he is begging for help and expecting you to be a kind person. — Sirius

But there is a difference between the illocutionary utterance (the declaration) and the interpretation whereby that utterance gains normative force. The request itself does not have that normative force. This is precisely where the "gap" occurs.
Language itself is normative — Sirius
I'm fine with considering this an "ought" statement in the same way that a moral one is. I also agree that the colloquial, illocutionary nature of the statement is confusing, though I think we could sharpen it up if we needed to.
But the problem is the same old one: There's an implied hypothetical between "I command you to" and "you ought to," namely "You ought to do this IF you want to keep your kneecaps intact" or some such. It's perfectly possible, though unlikely, that the hitman could reply, "I'm OK with broken kneecaps," in which case we haven't managed to derive a pure "ought" from an "is." This example certainly clarifies that the ought-is problem is logical, not psychological. Since just about no one wants to be injured in this way, the command has a lot of psychological force -- but no logical entailment without the "if" premise,
Language can be used to make normative statements.. Stating that language is normative is overreaching. Normativity describes a standard of behaviour. To the extent that behaviour and language do not necessarily coincide, language absolutely is not normative.
According to a prominent line of thought, the notion of correctness involved in the seemingly platitudinous claim that meaningful expressions have conditions of correct application is intrinsically normative. — Sirius
The "Is" is the utterance of the words, a fact. The "Ought" is the obligation.(i) Jones uttered the words "I hereby promise to pay you,
Smith, five dollars."
(2) Jones promised to pay Smith five dollars.
(3) Jones placed himself under (undertook) an obligation
to pay Smith five dollars.
(4) Jones is under an obligation to pay Smith five dollars.
(5) Jones ought to pay Smith five dollars — How to derive an ought from an is
The usage of "ought" for general normative statements is correct, since Hume wasn't only concerned with moral statements.
I don't see a problem with using colloquial language. In the philosophy of language, we don't look for a perfect language anymore. All we do is explore how language works in real life, following the example of Wittgenstein, who reminded everyone to let philosophy leave everything as it is
Determinism is true. So folk cannot be responsible for their criminal actions. Thus, we ought not punish folk for their criminal actions. — Richard B
Even if this is so, the issue is that the fact of the utterance implies the obligation.If I promise to do something it presupposes I have decided already that is the right thing to do. — Pantagruel
If you doubt this, then try and make a syllogism that concludes “you should kill Tom” is derivable with “today is Tom’s last day on earth” without simply making the latter an encrypted or ambiguated version of the former. — Bob Ross
Even if this is so, the issue is that the fact of the utterance implies the obligation. — Banno
