Remember the Erotica1 scandal? Please tell me what it had to do with "playstyle"
EvE devs started noticing around 2006 that multiple accounts enabled griefers and sociopaths, and ofc those accounts had to be funded ($ for CCP!). Devs did not address gameplay issues that allowed multiboxing, but instead, started to promote "Power of 2", effectively giving the signal that in order to compete in EvE, you had to buy multiple accounts and fund them, whether through RL money (easier and much faster) or grinding (and someone had to buy those PLEX anyway with RL money)
They cleverly understood that there was a niche in MMOs for griefers and anonymity-protected online sociopaths. EvE caters to them, but it goes much deeper than this.
Single shard -> high stakes because of reputation etc, so players take things at heart, and are ready to spend good money just to prevail in game.
Cue out-of-game money deals, so ingame player entities get harrassed, or don't get harrassed...
Plus the money laundering...
EvE is a cesspool, last thing DU needs is an input of its inhabitants
But as DU won't enable multiboxing because its gameplay is far from utter garbage, something tells me all the tryhards, RMT scoundrels and money launderers will stay in the containment universe known as New Eden.
