Earlier quoted context omitted.
If you built up a Linux system to have similar functionality (single user account across systems that syncs user data, automatically backs up to a cloud, syncs photos and videos, sends all traffic through an anonymizing relay, receives push notifications for essentially all apps, etc), would it contact fewer services?
To some extent. You could do a lot of the syncing with a decentralized system like syncthing. You could use GPS for time. Tor for anonymization and additional firewall-punching.
And by the time you get to nightly backups and photo sharing across computers, I think it’d be pretty similar.
