Fundamentally encryption is a tool, not unlike a gun or a knife. Encryption allows you to ensure your privacy. Whether and when a tool should be considered illegal simply because it facilitaties illegal acts, and whether privacy should be unlimited, depends on context. There's a balance to be made.
Country like Germany? They take privacy super seriously, almost certainly in large part due to historical reasons. Fun fact: this is why you'll also find far more blindspots on google streetview in Germany. Freedom of speech? Limited, for historical reasons. Privacy? Often far less impinged upon than the US, also for historical reasons.
So what's up with France, which this video is about? And the answer is relatively simple. France has had something like 40 islamist terrorist attacks since 2010. After 2015 a state of emergency was announced which lasted for two years. After that the state of emergency was formalised in law. If Macron hadn't taken these draconian measures, literal fascists (with ties to the Kremlin) might have won enough votes to form a government. France would have been ruled by the daughter of a holocaust denier and a Kremlin asset, right at the moment Russia invaded Ukraine (again).
So yeah, it sucks. But once you know the context, it's not that hard to understand the why.
A bit like how the UK is blanketed with cameras, and the UK's security services regularly spy on their own citizens. Also sucks, but the why is also understandable. A 30 year bombing campaign and almost civil war on British soil, followed by a spate of Islamist inspired terrorist attacks, tend to make a population more amenable to privacy violations.
