It's all about the almighty dollar, Terrin - always has been - always will be. The dollar in the pockets of the FF Multinational shareholder pockets, that is - not the dollar in the pockets of anyone dealing with or depending on the wild stocks that also compete with farmed product in the market.
It is way cheaper to pay the relative pittance to FF lawyers @ ~$400/hr and to stall changes to the industry's entitled and expected free pumping, free sewerage disposal and free real estate - than to give up a year or 2 in profits from the ONP sites - even tho the recommendations from the Cohen Commission were known way back in 2012 - 10+ years ago:

Ultimately those costs (elevated levels of parasites & diseases, along with potential & realized impacts) have been burdened onto the wild stocks so foreign multinationals can return more $ to their shareholders and CEOs whom don't depend on wild stocks and aren't negatively affected by those decisions, and likely have never even seen a wild Pacific salmon in person.
