Yes, it does. Even if it is "doomed from the start" as you put it, they're still going to make at least some of the money back. If they don't release it, they're gonna lose all 90 million. And I can guarantee you that losing 90 million dollars is going to hurt the careers of those who worked on this movie more than any potential backlash they might get from releasing it.
And even ignoring the money and the potential effect on people's livelihoods, there's also the effort that people put into this movie. Expecting people to throw all that effort in the trash because of random people on the internet thinking it's going to be a bad movie is not only stupid, it's downright childish.
This is also assuming that it is doomed. Despite the internet's backlash, the emoji movie made over 150 million dollars, who's to say that the same thing won't happen to this movie?
Edit: And you're also ignoring that the director simply isn't allowed to flush down the result 90 million dollars (yes, I'm gonna keep harping on about the budget) and 5 years of work down the toilet. The decision of whether or not the movie is going to be released is up to whoever owns the distribution rights of the movie.
