This is just a crappy article from a crappy mainstream media.
Now, France is definitely not the best place in the world for privacy-minded fellas. AFAIK, we're one of the last remaining western countries to have laws governing the import/supply of cryptographic tools1 (basically, you have to declare it to the French cyber authority). We have a law that defines a presumption of guilt when the way money is handled "can only be justified by an attempt to conceal the origin of funds"2, which now includes the use of privacy techniques in the context of crypto-currencies.
So yes, this police fella saying that "when this system is present on a mobile phone, it is a clear indicator of technical sophistication and an intent to conceal" is very concerning. But it's mostly that:
loads of people feel unsafe
most people don't care about privacy, even when we now have weekly data breaches (incl. quite frequently public services).
