Pope Francis has placed very significant restrictions on the saying of the old Mass, abrogating the much more permissive or generous policy of his predecessor Pope Benedict XVI. It is the pope's call to make. I hope people will accept it or work within proper channels to modify the restrictions.

Pope Francis himself could reverse it, or a future pope could. Nothing is written in stone. My worry is that the attempt to protect unity will become a trigger for greater division. That's the last thing we need just at the moment.
