Git open source agreement license comparison

Introduction to each protocol

protocol	brief description
Apache	Allow others to modify the source code and then close the source, but you must make a copyright statement for each modified file. Commercial, modifiable, and distributable, but declare the source of the author and your modification and agreement (many large projects use this agreement)
GPL3	No matter how the code is modified or used, it needs to be open source
WITH	Allow others to modify the source code and then close the source. There is no need to explain the modified files, and the secondary developed software can use the original author's name for marketing
BSD2/BSD3	Similar to the one above, but do not promote using the copyright owner's name or the names of its contributors without prior written permission
BSL	Similar to GPL, but does not require copying of copyright information
CCZ	Give up the copyright rights and interests of the created works and dedicate them to the public without any guarantee for the code
EPL	Similar to the GPL, the right to use, modify, copy and distribute the original and modified versions of the software, but in some cases the modified content must be released together
AGPL	GPL expansion, the use of online network services also need open source
GPL2	In contrast to GPL3, open source is not required if the code is provided as a service without distributing the software
LGPL	Compared with GPL, LGPL allows commercial software to use LGPL class library through class library reference (link) without requiring open source commercial software code
Mozilla	Similar to LGPL, but need to explain the modified source code content
Unlicense	Similar to CCZ, with open licensing of trademarks and patents used
