Folks here in Hawaii are split over this.
Many folks here have family on other islands, and travel frequently back and forth between the islands. When inter-island fares almost doubled after AQ collapsed in 2008, it caused deep resentment that still carries on 15 years later. These folks welcomed the arrival of WN for inter-island service and still harbor resentment against HA.
For those who primarily fly HA longhaul, they're more worried about losing HA's legendary "aloha spirit". I really like HA and their inflight service is truly welcoming, even though their website and underlying technology is a bit sketchy.
I welcome AS improving HA's technology platforms, but at what cost? HA is the largest private employer in Hawaii. If there's a massive shift in jobs from HNL to SEA, there's going to be some serious resentment.
Look, it's been swell, but the swelling's gone down.
