You do you but most businesses if given the option between supporting OAuth to reduce friction on signups, or only supporting password auth, will choose the option that makes them more money.

You don't have to use a 3rd party service for OAuth. You can do it in house.

Yea I know, I just don't want my app to have a google logo on it, or whatever other companies people use to login with. E-mail and password will forever be my go to solution.

I want intentional users not the ones that click "sign up with google", try out the app once and never come back. Also I don't have the time to learn how to properly integrate more auth methods into my app. I want my own user table, I want predictability on how a user model looks and I want to be in control of everything.
