What if it's a ploy from TT and Rockstar to drum up _even more_ hype around the game. People see the leaks and are like "holy crap, some of these look dope, I was skeptical but I might actually buy it"
Or it could be Netflix hyping up for their GTA VI reveal for a similar reason.
The GTA 6 leaker has continued to release new gameplay clips, and is even running a poll to decide which video to leak next despite Rockstar parent company Take-Two's ongoing hunt for people responsible. https://bit.ly/45EF4pJ
