Whenever a country moves in the direction of freedom it is a good thing, Bitcoin is financial freedom for everyone.
I can assure you that the government of Iran has no interest in giving its people any kind of freedom.
The transaction in question was intended to allow Iran to not have to use US and western financial systems. It was to evade sanctions against Iran imposed by the US. I don't think this is good for bitcoin or for crypto, as this shines a negative light.
