Try using UbuntuTouch for your mobile device, although you'll have to buy a new phone if yours is not supported. Using open software as much as you can will add another brick to the wall that tries fighting the monopoly. Brave for browser, DuckDuckGo for search engine, Protonmail for mail, Signal for messaging. Ditch Android, Facebook... etc. You know the drill!
