Many of the Nemotron datasets are gated behind approval, and a license agreement.

The preamble on these datasets is: "This repository is publicly accessible, but you have to accept the conditions to access its files and contents."

I don't know what others have experienced, but I requested access to multiple Nemotron datasets and those requests were ignored for months before all but one request was rejected. There's no explanation for why, nor anything I can see which would lead to a rejection. So it's purely anecdotal and YMMV, but I don't see these as being particularly open.
