I'd advocate for long-term harm reduction, myself.

While obviously it would be better for the cow to have been able to live a full life, but in (I think) 15 years or so that cow would be dead either way.

Something that can be helping new cows regularly, like a Beyond Burger that can appeal to those that would otherwise just pick a normal burger, I basically consider it to be harm-neutral after the lifespan of the animals they're using for those taste tests is up.

Honestly, this is the trolley problem. On the main lane, we have a bunch of cows about to be run over by our "Meat Industry" trolley. Pull the lever to redirect the trolley and butcher some cows for beyond burger development. I would pull the lever, but it's not a clear moral win.
