I'm fairly confident that the plant designers and researchers know this and that journalists have messed it up.

They're already pumping in 37.5B + 37.5*2.5/1.5B gallons of it, so pumping in a multiple of that is just a problem requiring money.

But getting the money to do so requires scaring the public into giving it to them, thus the scare articles like this one in the press.

> is just a problem requiring money

Any problem of providing fresh water for human civilization is "just a problem requiring money." It's not like there is a lack of water on the Earth. So it's kind of silly to pick one single particular aspect (diluting brine) to try to hand-wave away as just a money problem.

In general, money is a significant constraint on engineering and can't be hand-waved away.

Interesting. Why do you think this article will help scare the public into giving "them" the money? According to the paper linked in the article (Jones et al. 2019), many of these desalinization plants are in the Middle East and North Africa: "Brine production in Saudi Arabia, UAE, Kuwait and Qatar accounts for 55% of the total global share." Do you think that the general public in those countries reads Gizmodo and also has voting power to adjust the budgets for desalinization plants?

Also, why do you think that paper does not address the option of pumping in more ocean water and diluting it? (It's paywalled - if you'd like a PDF I can get you one.)
