An anonymous insider source shared some info about the cancellation. Might take it with a grain of salt, since it's from the word of a third party and it's uncertain how much of it is true, but apparently there's confidence in the information:

Some take away quotes:

"the cancellation was, quote, 'a 1000% upper management/exec issue"

"the decision to scrap the PvE was very much a decision motivated by Blizzard's profit margins, and that the success of Diablo on mobile, reportedly making over 2 million dollars a day, shifted the expectations of the higher-ups of the company"

"management kept starving the teams of resources without shifting the expectations to compensate, meaning when the time came to cut loose the PvE it was 'technically' because the devs 'couldn't meet their deadlines'. [..] Although it was once possible to finish the project, management eventually made it impossible"
