Google are the most literal incarnation of Big Brother I could possibly imagine at this point.
Try startpage or duckduckgo for search. (The prior is essentially a proxy for Google).
Fastmail or protonmail to get away from GMail. One of the hard things about avoiding Google in email is that even if you switch, others you communicate are likely still there, so Google's still getting that information.
Conversely, when I use google, I frequently miss !w (search on Wikipedia), !i (search images), !a (amazon) and other "bang" shortcuts.
E.g., in Chrome: Settings > manage search engines > find Wikipedia > change the shortcut to "w."
