The author is probably realizing increased productivity because Docker makes it economical to install these apps. Personally I would have also mentioned Zabbix, Wazuh, Mantis, Wekan and Rocket Chat as strong productivity enhancers (Rocket Chat is an excellent clone of Slack, and Mantis is a decent developer's ticketing system, which can be easily generalized).

But, I think the biggest advantage is not so much productivity as it is avoiding the Linux counterpart to "DLL Hell".

I also use Docker containers to run some legacy stuff like LaTeX, that often are not always up with the times. Many of the needs the author mentions I meet with good ol' Vim editor (many are not aware that it has decent built-in encryption features).

That very satisfactorily answers my question, thanks. Been there, done that.
