There is nothing in both Legends and Official Canon to suggest otherwise of Palpatine being the singular and all encompassing Galactic Emperor in SW History. So what he states is actual fact.

Leaks being “still up” doesn’t mean studios should rush releases. DMCAs aren’t about erasing leaks, but limiting reach and algorithmic spread. Trailers are tied to contracts, ratings, localisation, and marketing timing. Early drops often hurt coordinated campaigns more than they help.

No. The rest of the mainstream movie going audiences have no idea about leaks or anything. Just because a small percentage of the internet are in the know doesn't mean that they have to release anything for you. You are not the target consumer in the overall scheme.

I am. This is like the good old days.
