The vast majority of people, even fans of an artist, never find out about leaks because most people aren't as obsessive as we are. The only people who actually listen to a leak for the most part are fans who have already paid for the album and will be streaming it non-stop regardless once it drops. Maybe a few other people will hear it but it won't make much of a dent in the grand scheme of things. Leaks are also totally inevitable in this day and age. This one seems earlier than normal, which it is, but the delay plays a part in that, the original release date is next week and the delay happened fairly recently which was a poor decision on their part.
That being said, the circumstances around today's leaks are very unfortunate. It should never have happened on the same day as Lana's big award, and it should also not be happening with cringe tags from some weirdo who is desperate for attention. Listening to a full album leak may not technically be "right" but at least we hear the art the way it was intended to be heard, which in my opinion is the most important considering we've already paid for it. Lots of people hear albums early for one reason or another, music gets sent around to tons of people for different reasons. The general public still won't be hearing until release day.
