Why is The Flash still happening?

After everything surrounding Ezra Miller and their horrible behavior, I'm shocked that The Flash has still not been either completely tabled, or recast. Particularly with how willing DC was to squash Batgirl, you think they would be ready to make what seems to be a not so tough decision. It seems far more trouble than it's worth at this point, and seems relatively easy to recast with a new actor. What are they waiting for?
