I think people like Fortnite and PUBG because of concept for gameplay. These ones who wants to play BR but they dont have money the re downloanding fortnite. I think BR is too popular at this moment. Everyone wants to have his own BR game so on the steam and on the google play, app store etc. we can easly find hundrends of BR games (most of them aren’t even good).
Ive played both of them and I prefer to play PUBG because I think Fortnite is too fast and too chaotic for me but its still great game.
Probably in few next yers the’ll be relesed a new big BR game which will take the rule over BR games
