A butter knife works the same when cutting butter or steel. It still isn't useful for cutting steel. This is what they're trying to communicate.

A reaper drone works the same when blowing up random weddings or when flying in airspace with a networked AA system of S300s, S400s, and S500s

Which is to say we know the underlying physics continues to operate the same but the context changes how useful the equipment is, because a butterknife is made for butter and a Reaper is made for blowing up weddings without an air defense network nearby.
