The French flying clubs however still refuse letting their airplanes and members be involved in costsharing. The FFA is trying to provide a framework for costsharing within aeroclubs and has created a partnership with Wingly. I believe that what is referred above in terms of the certificate for costsharing is a FFA/Wingly thing and will therefore have no impact on operations with privately owned airplanes.
Perhaps not “no impact” if the aeroclub president has “influence” around the airport…. 
There is a lot of that sort of thing in GA, everywhere. Any aircraft owner will soon learn he/she has to keep their nose very clean.
Just give it some time, new ideas always create resistance from the old generation. Even the worst French aeroclub president will retire at some point. Wingly etc. are not pseudo-AOC for most part but incentives for pilots to do more flights which is good for airports and aeroclubs. Either pilots appreciate the cost sharing to afford more flying or (I think for the most part) they get reasons to go flying as opposed to be being bored flying all alone and eventually almost not at all anymore.
Now we just need to connect Wingly to Tinder…
