I stand corrected. It’s less clear which ones definitely need it, exactly. Wikipedia mentions that even Tc-99m generator designs can use low-enriched uranium. You don’t need large quantities in that case, either, since a little radioisotope goes a long way and there’s only so many people that need treatment.
Dating apps and similar with insufficient moderation come to mind, or even ones that effectively paywall dickpics and harassment instead of removing it.
For gender nonconforming people, lots of forms.
