Right now the salinity of the ocean is decreasing because of the polar ice melting. So to some extent, taking freshwater out of the ocean should be beneficial to preserving its ecological conditions.
It depends on how the brine is reintroduced, which I am sure will be up to the company or individuals will have some sort of collection for households. But salinity going down raises ocean temperatures, as I've mentioned in a comment down below so I won't really restate it gere.
