Note that he said "everyone's civil liberty". It means that he thinks that it is not everybody's right, not that it is nobody's right. They want to keep the right for themselves.

it's very ironic that they don't realize that this really doesn't work that way in practice

whatever backdoor you put in

- will be used for industry espionage

- will be used against politicians where it's supposed shouldn't apply

- will be used by state actors systematically destabilize EU countries if the relationship with US, China, Russia get's worse (e.g. "ups, I spoofed non encrypted message and no it looks like the prime minister is a pedo" kind of situations)

Because everybody knows that politicians are immune to the temptations of child porn...

Politicians' work emails are exempt, but private ones as citizens aren't

those are the only people who should never be exempt

Nope. That's not true. There is a provision that exempts people working for state security (e.g. spies), not politicians. Please don't make up stuff: this proposed law is already bad enough.

I think (or hope) that the point of the parent was to leak his emails anyway just so he gets a taste of what it's like for citizens to live in the society he wants to create. Personally I get the sense that politicians are too narcissistic to learn a lesson from that but it would still be fun.
