English has more roots in Germanic languages than in French.
Surely we should be blaming the education system that allows us to drop languages so early in school, and does not teach it early in primary school when languages can be most easily assimilated.
Europe used to publish everything in (I believe) three languages. The EU no longer publish in any other language than English, as this became too costly. The French seem happy with that.
Perhaps the onus should be on ICAO and not the French per se who are allowed by the ICAO rules to use mixed languages in this way, to ensure that only English, or whatever should be the clearance language with an emphasis on poor weather. The French do not break the rules.
Don't be so petty, and broaden your mind by learning another language.
