I recommend these easy first steps to #DigitalSovereignty for an average user:
1. Install
@signalappSignal, and *delete* WhatsApp
2. Start using #Firefox or
@librewolf with the
@ublockorigin extension
3. Start using
@libreoffice for documents and spreadsheets
4. Use a free opensource email client e.g.
@thunderbirdThunderbird: Free Your Inbox
All of the above can be done on non free operating systems.
Start experimenting with #Linux on a spare computer or laptop. All recommended software works there as well.
