Since the theatrical release of Justice League in 2017, fans immediately began campaigning for Warner Bros to release the original version of the film. As fans started begging for the Snyder Cut, Zack Snyder requested a meeting with studio executives.
As a matter of fact, Snyder met with Warner Bros execs three years ago to discuss the possibility of releasing the Snyder Cut. Despite it taking so long to actually release, the studio did at least hear the director out.
Warner Bros watched Zack Snyder's Justice League
Revealed in an interview with Vanity Fair, Snyder revealed that the studio has watched the original version of Justice League. It's ot clear what the studio thought of Snyder's original version in the face of the fan campaign. However, WB did watch at least sit through more of the film than the average viewer.
“I said, ‘Well, can I at least come in and tell you what I think the best version of this would be?’,” Snyder said. “And so I went in and just kind of pitched them on finishing the movie correctly and ‘Zack Snyder’s Justice League’ and how we could market it and what it would mean to the fans and all that. And then they came over to my house and watched it—no one had ever seen this version of the movie. They were like, ‘Okay, we’re inclined to do it.’”

When the time came for HBO Max, Warner Bros and AT&T agreed to release the Snyder Cut. Previously, WB suggested that Snyder could release the unfinished workprint without colour grading or visual effects. As we know, Snyder refused as it would've been a terrible version for the average viewer.
How the Snyder Cut came to be
Without the need for a flagship launch on HBO Max, we might not have gotten the released version of the Snyder Cut. With $70 million needed for Snyder to completely finish the VFX needed for a complete film, the movie needed a lot of hard work put in. With that money, Snyder got the best of the best, WETA Digital, to finish the movie’s CGI.
