This issue reflects the modern 'instant answer' world.
Selecting and preparing your own material is an excellent method to improve learning, and from knowledge of 'know what' provides a basis of 'know how' - how to adapt a flight technique for different conditions.
Plagiarising presentations might be acceptable to examiners, but this approach could assume that the student has critical skills of knowing what and how to research. If not, and this is easily established, then the interview could fail because of weaknesses in thinking, opposed to poor ILS knowledge.
Thus if a student is unable or unwilling to research the subject, to prepare thoughts, then these weaknesses are more likely to fail an applicant than the lack of a presentation.
Select for aptitude, train for knowledge.
A glib answer of how to fly an ILS is to 'follow the FD'; perhaps that is the reality of modern aviation - until you do not have a FD.
