Final answer:
Plagiarism definitions can vary across cultures, influenced by attitudes towards ownership. Developers release software under open-source licenses for collaborative development and community benefit.
Step-by-step explanation:
Plagiarism definitions can vary across cultures due to different cultural attitudes towards ownership and originality. For example, some cultures may value communal knowledge and sharing of information, while others may prioritize individual ownership and protection of intellectual property. In some cultures, there may also be different norms and standards for attributing sources and giving credit.

One reason is that it allows for collaborative development and improvement of the software by a community of developers. This can lead to faster innovation and improvement of the software. Additionally, developers may release software under an open-source license as a way to give back to the community or to gain visibility and recognition in the industry.
