Under the old Concorde Agreement (now expired), the FIA could only make changes to the Technical or Sporting regulations with the unanimous agreement of the teams.
The only exception to this was changes made on the grounds of safety, and Max has utilised this loophole to the full, bringing through a raft of changes that, on the face of it, had only a passing relevance to safety. After all, any change that influences the performance of the cars brings safety implications, doesn't it? The change from 3 litre V10s to 2.4 litre V8s was made on safety grounds despite strident opposition from several engine manufacturers, Toyota and BMW in particular, because of the additional expense incurred in the development of a whole new engine type.
As Bernie says, there are a number of areas within the sport where sporting and commercial interests overlap, and the FIA have been regulating for many years now in an attempt to "cut costs". Where they have not been involved, and are not likely to get involved, is in the matter of teams' income from FOM - this is what the EU were concerned about. Since Bernie has a seat on the FIA's World Motor Sport Council we might reflect on whether the separation of powers envisaged by the EU has been achieved in reality?
I oppose dictatorship in any form, and I wouldn't like to see a return to the days of the FIA acting unilaterally, as Balestre liked to do, without consultation or input of the teams. After all, the teams know the rules better than the rulemakers do, they know where the loopholes are and they know whether any changes are going to achieve their desired effects. As far as I know the FIA haven't got a full-scale windtunnel in the back garden at the Place de la Concorde...
Ideally everyone would be involved and this would foster a climate of trust and security.
