Okay. Allow me to rephrase it. Knowing what you know about these products, can you live without Google, Youtube, Gmail for a day? This is what I refer to above when I say 'the Internet'. I reckon most people can't go a week.
The only one of those I ever interact with on purpose is Youtube, only via youtube-dl, and only because other people refuse to use reasonable means of distributing video content (eg bittorrent).
Without bug problems. Migrating away from Gmail would allow me to de it indefinitely.
