Hidalgo did not mention Lucas and I see no evidence whatsoever to suggest he is still involved.
I’m not going to go searching for the tweet, but he was replying to someone’s question about it and said “there’s only one person who could authorize such a release, and he doesn’t seem interested in doing so.”
The “he” part would strongly imply GL.
Again, I’m not saying George has any real power, I think it’s more of an “honoring his wishes” type thing and Pablo not really knowing what he’s talking about.
