fucking annoying

security is annoying. You also have to carry around keys for your home, work, car, locker etc... Personally I think that is much more annoying.

can't believe they sold people that it's BETTER to have to get your phone out to login

Security wise it is better. Have you not seen a heist movie? There is always multiple layers of security. Two factor is another layer of your security.

incredibly annoying

Some passwords managers have 2FA built in. Just use that if your so annoyed. Less secure but still better than having no 2FA.

If you're using this willfully you're clearly just as worried about security as before anyway

I would be way more worried about an account without 2FA. Done right it is a huge security improvement.

Companies love having real phone numbers to pair with 'their' data

Good thing a proper 2FA system doesn't require a phone number. In fact using a phone number is less secure. So avoid giving out your number and use another option if possible.
