Is this not the best thing that could happen? Like now its in maintenance, it can be forked without any potential license change in the future, or any new features that are in that license change... This allows anyone to continue working on this, right? Or did i miss something?
Pretty sure you can’t retroactively apply a restrictive license, so that was never a concern.

It is useful to remember that one may fork at the commit before a license change.
