Well, their assumptions are based on the rumored numbers (150mil $ + 130 mil $ marketing) and the fact that Paramount only keeps around 50% of the box office earnings.
It´s something hasdi and I also discussed earlier.
The linked article is from a date before TLA was in the theaters, so mabye they aren´t haters, cause they didn´t even see the movie.
The article is just an analysis based on some assumptions.
I guess you didn´t even bother to check out the link, just calling anybody "haters" is so much easier.
