2FA doesn't automatically require giving any user data. Using SMS-based 2FA requires giving over your mobile phone number, but it's not like that's the only option available to you. TOTP gives the provider absolutely nothing, and has the added benefit of not being able to be compromised by a call to your mobile phone network or SIM cloning. You make this sound like it's part of a conspiracy to force 2FA on the unsuspecting masses so that the Illuminati can sell your contact details to aliens from Mars, or something. That's a bit insulting to the original poster, who is sharing useful information learned through real world experience.
