There are no positives here. Being the platform of choice for an irrational dictator is meaningless.
Im not against decentralization but to me decentralization=democracy, not anarchy. A community as a whole should be able to vote on whether it will refuse to support certain initiatives.
NEM does have a voting system about supporting projects, but that is only for asking the community if any funds should be given to project XYZ, not for whether project XYZ should be *allowed* to use the open source technology that has been developed. I don't think there is a way to prevent anyone from using it without making it proprietary (and not open source).
