I actually agree with you, but you're not 'right', it's your opinion.
I personally think it spoils the game, jump into an unknown system and see 100 carriers in the system map and you know immediately there's something special about that system, and the planet / gas giant with the most carriers will be the point of interest.
And yes, filtering them in the nav screen is a good first step but they need to be either removed or collated into one FC icon in the system map and trading menu's (especially as many of them won't even trade to other non aligned players).
