There are certainly stories of overzealous enforcement, but the context of Loi 101 and its amendments is worth considering.
Québecois is really interesting. It has a lot of old, outdated French in it due to the colonial connection with France being severed hundreds of years ago, where it evolved distinctly and the locals made different decisions on what to change and how to adapt to new concepts.
One could argue the French government has been obsessive about policing language much longer with the académie française.
What is interesting is how non-vocal many of these “concerned citizens” are when the criminal justice system does the same thing to normal people. It is why I have a difficult time believing the concern is really about justice and due process in many cases.
