I don't really see that as lazy. I see that as considerate/beneficial to the user. I much prefer to be asked in context what/how the app is going to use the microphone for rather than on initial install, when I might be like "why the heck does this app need to use the microphone?"
It was being used in the programming sense, not as an insult. When some code passes around a "placeholder" instead of a value and waits until it is used to bother calculating it, that is commonly described as "lazy".
