The not forcing ideologies on others bit. I'm not sure that it is that cut and dried. While there is on the one hand the history with the Gallente (and the current 'cultural imperialism' that Heth leveraged to stir people up against them), I don't think that forcing their ideology on people is something that megacorporations necessarily shy away from. At least, I think it is arguable.
As for PR, during my time in Naqam Izzy, Carcosa Hali, and I, among others, waged a fairly long PR campaign that was - I think - to some degree successful.
Of course, were I to go back to that, the more recent events would be a bit of a setback. :X
Although it is worth noting that the current Sansha invasion isn't out of line with Silver's public stance on the Nation. I took the easy way out, and said that the True Slaves were a tragic mistake.
Anyway, I can try and find some of that Pr stuff, if you're interested in the tack we took to try and portray the Nation as not the cluster's 'borg'.
