@Ravonna Firstly, I don't spread racist propaganda. Quite the opposite, but at least I wish we won't restrict each others right of fictional stories character, naming etc because of the anti-racist propaganda, especially since it has nothing to do with it at all.
Secondly, there are many webtoons that don't conform to this rule, like "Love your enemies", "Lookism" etc, where they are named the same even though they had prior fan translation.
Often times it doesn't make any sense, like when there are no illegal translations at all and they still change the title. It could be that they want to differentiate, but seems unlikely since there are many cases where the rule doesn't apply.
And especially in this case I am sure it's not the reason, considering they only replaced the word "white" in the title, not the whole title like they usually do. Not much intuition is necessary to figure out this case is off.
