The definition of “Free” has many definitions, but the most widely used is “free software.” In general, free software can be used freely, copied, changed, and studied by anyone. It can also be run by anyone and must be available as open source code. Free software must also meet specific criteria. Here are a few.
Programs must be able to be modified
One important element of a free program is its ability to be modified. This means that the software must be available in its source code as well as in binary or executable form. Without this, it is virtually impossible to study or modify the software. Other groups have created definitions of free software, including the Open Source Definition and Debian Free Software Guidelines. In both cases, the source code must be made freely available in the format preferred by programmers.
Programs must be in runnable form
In order for free software to be distributed for redistribution, it must be in runnable form. This form can be binary, executable, or source code. It’s important to distribute these versions so that free operating systems are easy to install. However, some languages do not support binary forms, so programs that are distributed in binary form must be made available in modified forms as well.
Programs must allow for redistribution
Free programs must allow for redistribution of copies in the binary, executable, and source code forms. Distributing programs in this form is essential for the development of free operating systems that are convenient to install. Moreover, it must allow for redistribution of modified versions.
Redistribution across income levels is difficult because it entails a huge amount of cost, making it inadvisable for government policies to directly benefit the poor. Redistribution across the income spectrum would also mean vastly increased taxes, causing a huge economic distortion. The highest rates would be imposed on the highest-income households, which generate the most employment. But if we aim to fight poverty, we must do it in a manner that does not harm other people.
