It’s generally older characters that fly freighters on average. The vast majority of freighter pilots should know by then, how to keep themself safe.
It actually isn’t hard, and as a freighter pilot, there is already so little risk of being ganked that reducing the risk even more just provides more ability to AFK play the hauling part of the game. For those of us that make ISK hauling, reducing the competitive advantage, by CCP making it easier for the lazy, would be terrible game design.
A while ago, CCP stated that when they make changes to the balance of ganking, that they like to do so in pairs - a buff in one thing balanced by a nerf in another. The two most recent changes have been nerfs to ganking freighters, so the next change should be if anything, a buff to ganking and not this proposed change.
