Many people are alarmed, thinking the hacker has a playable build that includes the game's ending.

Yes, that’s a possibility, but so far, we’ve only seen the small town where the story likely begins, Jason as a playable character (with whom we’ll probably tackle the first missions, while Lucia gets unlocked later), and a cutscene that looks like it belongs to one of those early, smaller missions. The hacker likely only has development footage from the game's initial stages—which is why Rockstar isn't worried about issuing a statement or making a strategic move.

It’s just a theory, but this is more entertaining than any marketing campaign Rockstar has planned
