No, you are not the only one! I have seen "upload" used in maker's literature for the copying of files from e.g. a camera or phone to a computer, and "download" for the reverse operation, so I can see that "download" might mean to copy data from a bigger or more central source to a smaller or more peripheral destination, and upload would be the opposite.
Maybe some people think "download" means "install", because that's how they get all their software...
Others that bug me are "memory" when they mean "hard disk drive", "cpu" when they mean "system case", "hardrive" for "hard drive", "reformat" when they mean "reinstall Windows" - (it invariably is Windows)...
