GPL 3.0 license is "non-permissive"

[timhettler]

Snyk reports that the GPL 3.0 license is "non-permissive". This raises flags in codebases that use Snyk for security scanning. (Including mine!) Unless there is a specific reason to use this license, would you consider switching to a more permissive one?
