You're thinking "drop" like a "drop point" where the binaries go after the build server is done with them. "Drop" in this case is like bike racing: "I dropped him on the last hill", i. e., I got rid of him by speeding up. "I dropped that like a hot potato" (picture holding a potato just out of the 200C oven with bare hands), a common U. S. phrase to indicate getting rid of something or having nothing to do with it.

So, Dropbox is dropping photos in the hot potato sense, not the build server artifact sense.
