Maybe I don't want islam to expand even more in France? It's usually Saudis who nag and complain about "lack of mosques" in Europe or USA.
Just out of pure curiosity from where did you invent/read/make such a conclusion?
How many Saudi Arabians or rich Arabs (Arabians) have engaged in terror in Europe? I don't think that you can even count 1. Despite millions of such Arab tourists in Europe. I have been in Spain, Italy, France, Greece, UK, Germany etc. and in most tourist hotspots I always see Saudi Arabian/Arab tourists from entire families to just young males to even females that are out alone shopping in London, Paris, Berlin etc.
Not once have I heard about any such claims. Even more so when there are mosques in most of those places.
But speaking about this topic, I have seen quite a few Youtube clips from American Evangelical Christians to European Christians and others complaining about why there are no mosques in KSA.
And once again, it is not the problem of non-Europeans that Europeans themselves embraced secularism and discounted religion. If not for mosques in Scandinavia for instance, aside from a few churches half-full during holidays, almost nobody in those societies would even worship God or attend places of worship. Instead many people (youngsters in particular) are worshipping "social media stars".
As for Arab money supporting mosques in Europe/West, I know the procedure behind this. Wealthy/rich/or people collecting money in those rich Arab countries are sending money to local Muslims in the West and their community (sending money to Muslim communities in non-Muslim nations are seen as a great deed in Islam - that money is spend on mosques, education, hospitals/Islamic schools and other institutions run by local Muslims who then spend that money how they please and appoint their own local clerics etc.
Every mosque in Europe/West is almost always funded by Arabs and secondary Turks. Whether local or outside support.
During my years in KSA (10 + years) I never met any extremist/so-called "Wahhabi" but in Europe many people (despite growing up in Europe) have beliefs that are not common in the Middle East and most of the extremism that they expose, are due to lack of integration, personal/economic/social problems and all of them use Islam as an escape goat. Which is why almost all terrorists/radicals in Europe have a criminal background. Also why the per capita quota of extremists/radicals/misguided people from Europe (European Muslims) is way higher than Middle Eastern Muslims regardless of country.
