Considering purchasing these upgrades has no effect on any other player other then the player who buys them this is win win.
You cant even show off the fact that you have these upgrades to others. There is no space pvp. If there was I could see the argument. I wont be buying these upgrades cause I can get them for free in game. I say good on EA for capitalizing on an area of the game that's entirely solo.
Again though, they balance the grinds so people P2W instead of doing the grinds, this has the inevitablc conclusion of meaning that player that DO NOT P2W have longer and longer grinds instead.
