Try turning off any of the incredibly invasive features in Android. If you try to turn off constant location, for example, maps starts throwing all sort of cryptic messages at you. You can't use google play without an account. They want to get you to log into Chrome so they can hook up your desktop searches to your mobile searches and profile you. If you've ever used Ok Google, every word you've ever said to it is recorded and stored in their servers.

Their entire existence revolves around extracting your personal information to sell you things, to profile you and sell that information to others to sell to you.

When you actually look at what they're storing about you Google's shockingly invasive.

They steal traffic and revenue from content creators, and are getting ever more brazen about it because they know the content creators have nowhere else to go. They use their dominance in search to promote their own sub-standard offerings, exactly as Microsoft did years ago. They've systemically attacked and destroyed other aggregators, while at the same time getting those aggregators to normalise that content so they can scrape and steal it in the form of data annotations, etc. to present the data directly to users without redirecting the user to the site that's actually provided the information.

It's not at all a noble cause and it definitely hop, skipped and jumped feet first into evil years ago.

And now they're trying to take over all mobile web traffic with AMP to lock everyone into their search platform.

They're evil coated in Engineer Cool to fool people like you.

EDIT: I do think they're a necessary evil though. If the government stepped in and forced web search to run as a public utility, which sometimes I think it should be, perhaps even at cost, it would decline.
