The small print in the contract
Windows dan Office adalah diberi lesen penggunaannya, bukannya dijual.
No one can buy Windows or Microsoft Office: instead users purchase a permission to use them. The license describes the terms of this permission. It is the restrictive legal text you have to click "OK" to upon install.
Anda akan kehilangan banyak hak untuk menggunakan perisian tersebut.
Terdapat beberapa sekatan yang mesti anda terima mengikut perundangan. Restrictions on who can use the software, what kind of revenue you may earn with it, on how you choose to install it, restrictions on your privacy, even on whether you can give it away: the list is long. Reading the license and enumerating your remaining rights is itself a difficult task.
Perisian edaran OEM-tidak boleh dipindah atau dipasang ke komputer lain.
If you bought your computer with Windows or Office pre-installed (the so-called OEM licenses, or the "shrink wrap" Windows discs), if you change computers you must buy software again. Lesen yang diberi hanya pada satu komputer, dan menjadi luput jika komputer rosak atau tidak boleh digunakan lagi. Ia menjadi kesalahan jika anda memindah atau memasangnya pada komputer lain.
If you go to most of the free software sites you can click down a couple of levels and find the [GNU] GPL, the X license, the Apache license, whichever terms and conditions you have to accept in order to use that software.
Now with a proprietary software company, the license is buried so you can't read it until after you have paid for the product, then they're asking you to turn off part of your brain, they're asking you to turn off part of your ability to work with other people and to do business, when you use their software.Don Marti, Temuramah 2005
Companies like Microsoft like to assimilate their software to physical products, when mentioning copyright infringement for example. Yet, proprietary software is very different because of the restrictive license -such restrictions would be unthinkable on a car or bicycle, for example.
Restrictions on the use of Office and Windows are so harsh, that many violations occur everyday around us. People are tempted to buy only one version of Microsoft Office and install it on two computers. Others keep their version of Windows when they throw their PC away. Other people give away their second-hand Windows software when they stop using it.
You have an alternative to breaking this law, or feeling very restrained when you abide to it. GNU/Linux is Free Software (much better than just freeware): its GPL license is designed to protect your rights.
