Hexor, when the game released we played with 7000 players. We had 50 players per match filling a server within a minute. At that time I already posted a message on this forum about increasing the player count to 75 or even 100 and that it would be better using whole map and not indicating the safe zone while still dropping in the air. So people would spread out on the whole map before the first safe zone would be announced. I think it would have helped to keep more players in the game because even with that 50 players most were dead within a minute leaving only 15 to 20 players alive during the rest of the match.
At this moment it has no point anymore to increase the player count indeed. Only when more players buy the game again or play it in free weekends for example. Then the servers will be full again. And only then it’s possible and making sense to increase the player count per match if they are ever intending to do so.
