I think that would have been a reaction that many others might also have. CCP have noted in the last couple of years that the confusion around loss (not ganking specifically, but loss overall) as a new player is a reason they believe contributes to poor retention. Not the loss itself, but the confusion around how/why it happened.
At the same time, they’ve also noted that ship loss in pvp is the #1 factor that correlates with higher retention of new player after 3 months.
So while there are players that might negatively react to being ganked as a new player and leave, there are also players that come to the game for it’s reputation for big fights and harshness, but then never experience anything like they it, and leave quickly because it’s boring. They don’t experience any loss at all that hooks them.
Ganking is one of those few things that provides that experience in highsec; and based on CCP’s more recent indications, it’s not ganking that should be prevented, but more should be done to ensure new players understand the why and how, so they aren’t confused when it occurs.
In addition to that, there is an old Law, Malcanis Law that applies equally today as it did previously - any change introduced to specifically benefit new players, will overwhelmingly benefit veterans more.
There are many ways ungankable new characters could be exploited by vets, especially with skill injectors.
For example, skill inject straight into a freighter pilot and be unkillable, even on autopilot for the invulnerable period. Just autopilot around highsec without really playing the game at all for long periods of time.
That’s just one example. There are many that can (and have previously) been thought of.
I don’t think that would really be good for the game at all, although both CCP and the community should always be doing more to inform new players of the risks they face, rather than just removing those risks all together.
Ganking definitely makes EVE a better place in that regard.
