Is Django not FOSS?

Interesting discussion in the article. Seems like it's a pretty experimental therapy atm without any conclusive evidence that it works.
And Rocketchat and Gitter (now also matrix)...
Good job and thanks for the questions.
It is. I tried using it for a larger project as replacement for Google docs and mostly that's fine but we needed sheets and later also appscript to communicate with email so that we moved back. I'd highly recommend cryptpad though for anything that has slightly less advanced requirements.
Kobo Glow here. It works fine, no larger complaints although small things could certainly be improved. The most amazing thing is that I'm using it for about 10 years now. Battery is a bit weaker but still OK. It'd be nice to have more devices with such a lifetime.
Cryptpad is using a custom, zero-knowledge Version of only office. They describe the relationship between both here: https://docs.cryptpad.org/en/FAQ.html#what-is-the-relationship-between-cryptpad-and-onlyoffice
