Earlier quoted context omitted.
From the article: > One plaintiff in the lawsuit is a crypto investor who used Tornado Cash to send funds to support the Ukrainian war effort, hoping to preserve his anonymity and avoid retaliation from the Russian government.
Ok so a user who already has crypto and doesn't want to convert it first (fees) may be encouraged to mix it (privacy) and that is a legitimate usecase. That makes sense to me, though it seems like a very rare event that should not be the sole basis for the underlying platform. Also I should've read the full article first.
I would assume making a nontrivial donation in fiat privately is also very difficult.
