I’d just like to interject for a moment. What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux,” and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use.

Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.

Didn’t know we had that in France, never heard of anyone paying a fine other than a fixed amount (and 90℅ of the time 135€)

That’s exactly what I said, each side of the bridge has its own encryption standard (or no encryption at all).

The encryption could be as solid as possible, the problem would remain unchanged: to bridge messages between two services that are not interoperable, you need to decrypt them at some point.

Let’s

Matrix bridges have nothing to do with encryption, they read the messages exactly the same way a client would, and send them to the other side of the bridge exactly the same way a client would.

It’s only for the free tier, and it’s removable, just a little annoying cause you have to do it every time you write a mail.
