Yes. (However that does not mean you have to pay for it).
I attach a link below to explain.
The open source uses a "copyleft" copyright licence - The GPL grants the recipients of a computer program the Free Software Definition rights and uses copyleft to ensure the freedoms are preserved whenever the work is distributed, even when the work is changed or added to.

Facts which are not considered common knowledge should be cited, regardless of copyright. Wikipedia articles, for example, should still be cited.
The Computer Software Copyright Act of 1980 extended copyright protection to computer programs, recognizing them as literary works under U.S. copyright law. This legislation aimed to safeguard the rights of software developers by preventing unauthorized reproduction and distribution of their programs. It also clarified that both source code and object code are eligible for copyright protection. Overall, the act helped foster innovation in the software industry by providing legal protection for creators.
Conclusion of the latest open source software available and the latest development in ict
Yes, provided the source code of the changes is published freely and that the open source licence is applied to the code changed.
The notification may be at the bottom of each page (as here), on a separate "about" page, in the source code, or nowhere at all. A notification is not required for protection.
That would be considered "open source" software.
Commonly "poor man's copyright" refers to sending a copy of your work to yourself by registered mail. Theoretically this establishes a date of completion (assuming the Postal service is a "trusted source") Bear in mind however that there is no provision in copyright law regarding any such type of protection. Poor man's copyright is not a substitute for registration and until tested in court is best regarded as an "urban myth".
Typically, the source of the data controls the copyright. For example, when a journal search turns up an article from the Lancet, the Lancet still holds the copyright on the article.Some data generated and/or collected by the federal government may not be subject to copyright. For example, geospacial data collected by NASA is not protected by copyright; however, a private company can arrange the data in a way that may be copyrightable.

Yes, you can copyright an app, but it's important to understand that copyright protects the specific expression of ideas rather than the ideas themselves. This means the source code, graphics, and audio used in the app can be copyrighted, but not the underlying concepts or functionalities. Additionally, you may want to consider other forms of protection, such as patents for unique features or trademarks for branding.
US Code Title 17 Circular 92 is a good source for copyright and related laws.
