#AI is powerful because the results are transferable from one domain to another.— Michael Krigsman #CXOTALK (@mkrigsman) November 2, 2018

In London this week for Microsoft's Future Decoded event, according to reporter @richard_speed of @TheRegister, Satya Nadella asserted that an AI trained for one purpose being used for another was "an unethical use".
If Microsoft really believes this, it would certainly be a radical move. In April this year Mark Russinovich, Azure CTO, gave a presentation at the RSA Conference on Transfer Learning: Repurposing ML Algorithms from Different Domains to Cloud Defense.
Repurposing data and intelligence - using AI for a different purpose to its original intent - may certainly have ethical consequences. This doesn't necessarily mean it's wrong, simply that the ethics must be reexamined. Responsibility by design (like privacy by design, from which it inherits some critical ideas) considers a design project in relation to a specific purpose and use-context. So if the purpose and context change, it is necessary to reiterate the responsibility-by-design process.
A good analogy would be the off-label use of medical drugs. There is considerable discussion on the ethical implications of this very common practice. For example, Furey and Wilkins argue that off-label prescribing imposes additional responsibilities on a medical practitioner, including weighing the available evidence and proper disclosure to the patient.
There are often strong arguments in favour of off-label prescribing (in medicine) or transfer learning (in AI). Where a technology provides some benefit to some group of people, there may be good reasons for extending these benefits. For example, Rachel Silver argues that transfer learning has democratized machine learning, lowered the barriers to entry, thus promoting innovation. Interestingly, there seem to be some good examples of transfer learning in AI for medical purposes.
However, transfer learning in AI raises some ethical concerns. Not only the potential consequences on people affected by the repurposed algorithms, but also potential sources of error. For example, Wang and others identify a potential vulnerability to misclassification attacks.
There are also some questions of knowledge ownership and privacy that were relevant to older modes of knowledge transfer (see for example Baskerville and Dulipovici).
By the way, if you thought the opening quote was a reference to Spiderman, Quote Investigator has traced a version of it to the French Revolution. Other versions from various statesmen including Churchill and Roosevelt.
