I don’t think so and again I do not believe this is only about profits and definitely not about retaining players who might leave the game otherwise. They have done plenty of nerfs to income in recent years and it hasn’t had any significant effect on the player count despite a lot of statements in protest claiming as much on the forums.
It isn’t about the price of PLEX either but simply keeping a balance between the producers and consumers of PLEX in the game which is directly related to how much wealth players gain whether that means buying more PLEX with ISK than is bought directly from CCP with real money or having no need to buy PLEX from CCP because it is easier for players to produce ISK to gain PLEX instead.
This doesn’t even include diving into the effects on game play itself when players have too much wealth income in general. I am sure there is much that can and has already been said about that in many other topics on the forum’s history.
CCP isn’t on the ropes for finding ways to make a profit out of this game and in some ways it could be a benefit to both CCP, players and the game itself if there were less players in some context.
That is just my opinion and I can only divulge into speculation about CCP’s true intentions.
