For Utah because it is still majority male and someone willing to donate a ton of money to start the program. It would probably be tough for all 3 but at least Utah's decision can push them some. There is a reason why Michigan is the only P5 school to start a lacrosse program in the last - what 25 years - in overcoming Title IX. Something Utah didnt truly face.
I guess the issue for Stanford is that they already have a women's lax program so there isn't an offset on the female side that can offset the starting of a men's program.
