The rumors about it coming out on HBO max makes perfect sense. Even if it's not ready for launch, if they're smart it will be there soon after. HBO max doesn't really have a lot going for it, and the rates are a lot higher than most streaming services.
i agree this is the perfect opportunity for warner to finally invest in this release, especially considering all other movie production is shut down for the unknown future due to covid. However, it also makes it nearly impossible for Snyder to film the additional scenes he needed to finish the film. Unless filming said scenes could some how be done with the actors isolated from one another, but it would cost even more in post production to seamlessly blend this footage together to make it look believable.
