I wonder if anyone still wants to know...
I'm doing freelance work for Swisscows and they told me that Protonmail has a master key to unlock any encrypted data. With Swisscows this doesn't exist, so even the meanest of governments could force them at gunpoint to surrender data, and still they wouldn't be able to.

Proton for Business accounts use end-to-end encryption(new window) to secure emails. This is achieved using a master encryption key called the organization key, which nobody other than the administrators of your organization has access to.

Because even we do not have access to this key, your data remains private, even from us.

This is a system daemon for the Linux kernel that eliminates the need for large, fixed swap partitions.

Usually when you install a GNU/Linux system, it sets up a swap partition on disk. The swap partition serves as virtual memory, so you may need a lot of it. But you can't store data there, so you don't want to sacrifice too much disk space. And it's not always easy, or safe, to change its size afterwards!

Running swapspace solves that problem. You no longer need a large swap partition. You can even do without the whole thing. The program manages swap files for you. These work just like partitions, except they're normal files. You can add more when you need them, or delete some when you want the disk space back. And that is exactly what swapspace does. It constantly monitors your system's virtual-memory needs and manages a pool of swap files accordingly.

With swapspace you can install GNU/Linux in one single big partition, without regrets later about picking the wrong size. Your system can handle the occasional memory-intensive task, without eating up disk space that you'll never get back.

"Integrate good code from any source with acceptable licenses. ISC or Berkeley style licences are preferred, the GPL is not acceptable when adding new code, NDAs are never acceptable. We want to make available source code that anyone can use for ANY PURPOSE, with no restrictions. We strive to make our software robust and secure, and encourage companies to use whichever pieces they want to. There are commercial spin-offs of OpenBSD. "

"GNU General Public License, GPL, LGPL, copyleft, etc.

The GNU Public License and licenses modeled on it impose the restriction that source code must be distributed or made available for all works that are derivatives of the GNU copyrighted code.

While this may superficially look like a noble strategy, it is a condition that is typically unacceptable for commercial use of software. So in practice, it usually ends up hindering free sharing and reuse of code and ideas rather than encouraging it. As a consequence, no additional software bound by the GPL terms will be considered for inclusion into the OpenBSD base system.

For historical reasons, the OpenBSD base system still includes the following GPL-licensed components: the GNU compiler collection (GCC) with supporting binutils and libraries, GNU CVS, GNU texinfo, the mkhybrid file system creation tool, and the readline library. Replacement by equivalent, more freely licensed tools is a long-term desideratum."

Commercial software

“Commercial” and “proprietary” are not the same! Commercial software is software developed by a business as part of its business. Most commercial software is proprietary, but there is commercial free software, and there is non commercial nonfree software.

For example, GNU Ada is developed by a company. It is always distributed under the terms of the GNU GPL, and every copy is free software; but its developers sell support contracts. When their salesmen speak to prospective customers, sometimes the customers say, “We would feel safer with a commercial compiler.” The salesmen reply, “GNU Ada is a commercial compiler; it happens to be free software.”

For the GNU Project, the priorities are in the other order: the important thing is that GNU Ada is free software; that it is commercial is just a detail. However, the additional development of GNU Ada that results from its being commercial is definitely beneficial.

Please help spread the awareness that free commercial software is possible. You can do this by making an effort not to say “commercial” when you mean “proprietary.”

"BSD systems

FreeBSD, NetBSD, and OpenBSD all include instructions for obtaining nonfree programs in their ports system. In addition, their kernels include nonfree firmware blobs.

Nonfree firmware programs used with Linux, the kernel, are called “blobs,” and that's how we use the term. In BSD parlance, the term “blob” means something else: a nonfree driver. OpenBSD and perhaps other BSD distributions (called “projects” by BSD developers) have the policy of not including those. That is the right policy, as regards drivers; but when the developers say these distributions “contain no blobs,” it causes a misunderstanding. They are not talking about firmware blobs.

None of those BSD distributions has policies against proprietary binary-only firmware that might be loaded even by free drivers."
