"Why are they choosing the GPLv3 plus this additional permission?
"According to the project, "We believe this additional permission enables wider use of Canola2 in different kinds of business models and product offerings, especially in CE devices. This additional permission combines the best parts of GPLv2 and GPLv3 experiences. We encourage other projects to consider use of this additional permission if they have similar needs."
"What is the specific permission language?
