This is not an issue of someone's paranoia or being overly concerned about the notion that books, music and other art can be taken from someones computer via online storage and used to assist the person who has taken it for their own use in creating a book, music or art without actually ever creating the work itself. The issue of argument is that once work is released to the public domain in that it becomes stored in some capacity(some far away server where people who look for ways to make money may be able to access information on the server), without the proper protection regarding copyright or trademark then the risk of having your exact idea duplicated is one that should be considered because it is very possible.
Computer software makers emphasize the flexibility involved in using online storage because of it's ease in access so that one no longer needs to carry external storage devices. This also makes tablets and smartphones seem attractive enough to buy in place of a computer if you are able to download a version of windows, word ect.. On these devices you may also have a micro storage card that you can store things like pictures on, but the reasoning behind cloud computing is to make tablets, smartphones, desktops and laptops smaller and lighter and without optical disk (cd/dvd) use so that these computers are not bulky resulting from storage.
Although computers still provide options for storage capacity, due to online storage and cost effective measures companies may choose when making a desktop or laptop computer loads of storage may not be available on the newer computers. Lets just say, that a computer maker can save millions of dollars by creating computers with 1.5gb of storage and that computer maker enters in a deal with a cloud computer vendor for online storage. This would mean that once you purchase a computer from that computer company you will only have a computer with 1.5gb and to provide yourself with additional storage you will need to sign up with the online cloud computer vendor to get at least 3gb for free; anything after that will cost you per year. This means that you now have to pay for storage, and risk having your uncopyrighted or untrademarked works available on a server for someone to locate and use if they are able to.
Cloud computing should be a choice or option and not set as the standard or automatic way of storing files. There should be no defult setting that allows any set of files, documents or works to automatically be sent to a cloud computer storage server even if you did purchase the computer given the knowledge that additional storage would have to be obtained through a particular cloud vendor. Cloud and online storage vendors will claim that they are not held liable for files and documents that were obtained through their servers and duplicated by someone else as their own set of works, music or art. Which means that if your work is not copyrighted or has not obtained a trademark it may be very difficult to prove in some instances that your work was not plagiraized.
There is no denying that cloud computing is of benefit to the user when he or she needs to access information from any computer. But it still should be a choice to the computer user since people who intend to copyright or trademark works don't intend to share their art with the world without protecting it first. Think about it, everbody will come out with the same book,song,work of art, product and what not! Without a copyright or trademark there is no infringement. The fringe benefits of cloud computing, to cloud compute or not should be an option!
