Examples of such open source licenses

[Joywtome231]

Although at first glance licenses and open source seem to be very contradictory concepts, practice has shown that legal regulation is necessary here. Initially, open source supporters rejected formal license agreements. But later it became obvious that any freedom requires a certain order, especially if it is related to intellectual property.

In the case of an open source product, the license is not a set of restrictions. Rather, it is an agreement that sets the rules for interaction between authors and users.

When studying open source licenses, you may come across the following terms:

Permissive licenses
These licenses are unrestrictive. They impose virtually no restrictions on how the program can be used. In addition, you are allowed to choose any licenses for developing products based on them.

Examples of such open source licenses
MIT is a very common license because it imposes almost no restrictions. You are free to jordan phone number list use, modify, share, and even sell your product with this code. There is no requirement to provide source code. The main thing is to indicate the author and not to declare any guarantees.

Apache 2.0 – puts an emphasis on copyright. You must specify the authorship in each file or in a special NOTICE file. If you use someone else's component under Apache 2.0 with its NOTICE file, you need to include it in your product. This license allows any type of licensing of your product, it only requires specifying the authorship and changes.

BSD — differs in the number of conditions. If it has only two clauses, then it is almost as free as the MIT license, and allows free use and distribution of the code. However, if there are three or four clauses, then additional restrictions appear, for example, stricter adherence to the rules when reusing the code.

Copyleft
These licenses allow you to freely share copies and create products based on them. However, there is an important condition: any developments derived from the original must be distributed under the same conditions and keep the software open. For example, if you use someone else's library with such a license in your project, your project must also be under this license.

GNU General Public License (GPL) - This license requires that you make the source code available when you distribute the program, even in compiled form. If your project includes GPL-protected code, the entire project must be distributed under the GPL. The same rule applies to modifications and distribution of the code.
