Not even remotely in such invasive way Google does it. On Reddit you can still register without email, through Tor if you want and the only problematic thing they changed recently is requiring javascript to comment and vote.

Meanwhile Google requires your phone number, your emails (which it shares with humans in other companies, like literally random people reading your emails), tracks your location even if you disable location services, tracks your every word typed on stock Android keyboard, every installed application and how you use it, your voice, your outside life habits, your digital habits - imagine living with a team of sales people living with 24/7, making and sending every most private detail of your life to more humans all over the world and making permanent record of every embarrassing moment in your life.
