Due to many reasons, main ones are follows: 

1. It is computer science program, and not philosophy program. Certainly, foundations are in philosophy (mathematical logic), but curriculum focusses on well-established topics (immune to philosophical objections). 

2. Expectations from the program are to produce engineers and technical researchers, not philosophers. 

3. Undergraduate curriculum is fully packed. Literally, it is packed with assignments, lectures, tutorials, labs. You don't want to bother undergraduates with philosophical problems -it defeats the purpose of the program. There is too much already. 

4. Philosophical points of view are not completely ignored. They are mentioned, in passing, in selected courses -theory of computation, logic, etc. A genuinely interested candidate *will* eventually investigate theorems of Godel & Turing. In that sense, it is best to let students who are able to *see* philosophical problems approach on their own. Why impose things which don't make sense universally -it is philosophy after all, and this is not a philosophy program.
