I wanted to point out a workshop and related talk coming up this weekend at LibrePlanet 2021 folks here may find useful. Both feature Nextcloud as a central feature of a healthy, freedom-respecting digital life.
The first is a workshop: Free Software Data Fortress For Your Home. (See also: LibrePlanet 2021 — Workshops ).
The second is a talk: Here’s how you can get all your day-to-day computing done with free software.
I hope this is helpful.
