If my app uses Google login, an I not allowed to count those users because I simplified their sign up flow too much? Your stance on this basically makes no sense.
instagram and threads are both social apps owned by a large social app giant and they launched right when people were getting pissed off at Elon’s twitter
calling their DAU numbers anything but a perfect storm doesn’t make sense—your app wouldn’t push messaging to every google user to join, and you don’t own Google OAuth and users, Google does.
