isn't that a backdoor?

To me, a backdoor is passive. There for someone to enter. What's under discussion here is sonething active, so in some sense worse.

I think this is more the entire front of the house being open to the street.

To be honest, I’m starting to consider this more a front door. You don’t need to break encryption if you can just bypass it.

Backdoor kinda implies it is not used very much or it would be a front door.

But it is available for use. Corruption is not a fantasy but a reality. Usually who reach the top on political scale have seen it all, I mean all. Being polite to describe this reality use cases, (inside trading, political targeting, discrimination, monopoly etc). Who would know, who can stop it, who would dare!

What are the protection mechanisms? Are we suppose to hope that the untouchable/s is 100% honest?

It feels uncomfortable to say the least.

I was arguing if the "backdoor" is not secret or atleast seldomly used it is a ordinary door.

Chat Control would always spy on people and thus not be a backdoor.
