I am wondering if we can omit "the" in the case we want to warn someone against "the use of something?". For example:
On an airplane in some countries, (the) use of any electronic devices is firmly prohibited.
In the classroom, (the) use of electronic devices such as smartphones are unacceptable.
In this case, "the use" of electronic devices is very ambiguous. What I mean is that we don't how what people are going to use the devices for; they can calling, texting, playing games, or even prohibited dangerous stuff. The range is too far for putting the term "the" in the sentence.
That's just my assumption. I am open and forward to hearing from every one in the forum.
