On: .name Grandfathered

I have bought my *.name domain a decade ago? Why was this ever a thing? Was there some limitation i'm to stupid to get or did one company just register some common last names?

for specifically third level registrations

So they offered third level registration for all non taken domains?

They only allowed third level registration for years and opened up second level registration much later in a profit seeking move.

The TLD was created in the "email will be THE way to contact you digitally" hype and marked on having a first@last.name email.
