It is. Sometimes the writer will add "didn't respond before press time" to give a little more context, but most readers won't grasp what that could really mean (like the reporter might have contacted them 15 mins before press time)

Do you have any examples of stories where one of the subjects was contacted, wanted to respond, but didn't have enough time?

Here's a current story. No idea of this news source but it is widespread. CNN is in a defamation lawsuit directly related to not waiting for a response to straighten out facts.
