Need for Robust Contributor Policies:

Successful open source projects require more than just a permissive license. They need strong Contributor License Agreements (CLAs) and clear policies on community contributions. Without such measures, projects might experience issues from anonymous contributions or misattribution, leading to legal disputes.

Key challenges summarized in bullet form:

Exploitation by commercial forks without mandatory compensation.
Legal ambiguities when integrating multifarious licenses.
Lack of native support for modern blockchain-based compensation.
Risk associated with contributions from unverified sources.

Future Outlook and Innovations

Looking ahead, the evolution of open source licensing is poised to adapt to modern challenges. Here are some trends and potential advancements:
