Thank you for the suggestion. GPL was, indeed, my first choice, but I have a (maybe inaccurate) impression that commercial users tend to dismiss software based on it, even for GPLv2, unless it is a project with a lot of traction, such as the Linux kernel. Currently, my favorite is the Mozilla Public License (MPL) 2.0, discussed e.g. here: https://fossa.com/blog/open-source-software-licenses-101-mozilla-public-license-2-0/ https://fossa.com/blog/open-source-software-licenses-101-moz... Any opinions are welcome, thank you again :).
