They use Google tag manager in their signup page. Translation, Google will know your user name, tie it to your real identity, and will track everything you say.
They'll track everything you share, like, comment, etc. You're helping them build a profile on you. Unless you're completely insulated from all advertising, they will find ways to "nudge" you into making purchases and forming opinions.
Nudging is a slow process that happens on the subconscious level: https://www.convertize.com/what-is-nudge-marketing/
Nudge marketing refers to deliberately manipulating how choices are presented to consumers. Its goal is to influence what consumers choose, either to steer them toward options that the marketer believes are good for them or simply to stimulate purchases and increase sales
Don't use Chrome, it shares everything with google. Use Brave which is based on Chrome, and turn everything OFF in privacy settings except for the Do Not Track option
Another good choice is Firefox. Completely different engine (gecko) than chrome and all the others (chromium). One of the last that is truly different, with good security.
Brave is no better but dumbshit op is still thinking he knows anything about privacy and the internet lol. Unless you've stayed completely off the grid with zero modern technology then you should know that they too 'have it all'
This
LOL at the fucking morons down-voting Firefox. Fucking ignorant sheeple. Do some research before blindly parroting things you yourself do not understand.
