Call me pessimistic if you wish but I foresee the time of companies taking
permissively licensed codes, adding a few features and releasing the whole as
proprietary programs. t3g is a precursor.
It does not require much work and, unfortunately, people who do not value
their freedoms will prefer the proprietary versions and their few additional
features. As long as the free versions are developed, the proprietary
versions get those developments for free (while the reverse does not hold
since the source codes of the proprietary applications are unavailable). Time
after time, the proprietary versions get more and more distinctive features,
more and more users... that is less ans less users/developers for the free
software versions. The proprietary software editors may even manage to hire
some developers of the free software versions.
In my opinion, the GNU GPL still is the way to go for the vast majority of
applications.
