I am working on a piece of embedded software for a consumer device. For a small part of the software, we are using a third-party library that is licensed under the MIT license.
As the MIT license states
The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
the question arose if we have an obligation to mention the MIT license and/or our use of the third-party library in the documentation that comes with the device.
We are not distributing the source code to anybody, but we are obviously distributing the binaries as part of the consumer device. And as the device is not capable of showing texts to the user, it is not possible to physically keep the license text with the binaries and show it on the device itself.
