@ube @eliseo01 @lain I agree - you should be free to not share what you made, by being free to not distribute the software (some "open source" certified licenses don't actually give you that freedom).

But, if you are distributing a modified version of the software as proprietary software, you are taking freedom, as the user would have freedom if you just kept the freedom in place and included or offered the source code as free software via some reasonable method (which the GPLv3 & AGPLv3 define).
