Key Benefits of Apache 2.0

Patent Protection

Unlike simpler licenses like MIT, Apache 2.0 includes an express patent grant from contributors to users. This means that if a contributor has patents that cover their contribution, they automatically grant you a license to use those patents.

Clear Contribution Terms

The license explicitly states that any contributions are assumed to be under the same Apache 2.0 license unless otherwise specified, providing clarity for collaborative development.

Compatibility

Apache 2.0 is compatible with many other open source licenses and is widely accepted in both open source and commercial contexts.
