At home, my parents are forced to use Windows and macOS because of their work, but all the machines at home are either Linux or a Linux/Windows dual-boot. The mobile phones run LineageOS. I haven’t succeeded with my little brother, who’s the only one with an iPhone.
Everyone’s happy, and when there’s a problem (which happens quite rarely), I’m asked, and it’s solved in seconds. Most of the time, no one misses proprietary applications, and everyone’s surprised that everything’s free, hahaha.
