Thank you very much.
I also have this question as to whether it is a legal way to present licenses because it is not so easily accessible. But on the page says it is as one of the possible means "Output Log".
And early on it says:
"The license does not specify how it has to be included, so anything is valid as long as it can be displayed under some condition. These are the most common approaches (only need to implement one of them, not all)."
It would then be a valid means because "...it can be displayed under some condition" anyway, even if only connected to a PC?
