DOT rule would require airlines to issue refunds for domestic flights delay

All it does as proposed is to make it so you're entitled to a refund if the delay is over 3 hours. I think that means you don't fly, you can just get refunded and go home. That is like not a penalty. It does not appear to be compensation/refund on top of getting to complete the delayed flight, at least from what's in this article.
It did not increase price and it provides a straightforward compensation. I've received twice a compensation for work travels (doesn't matter who paid the ticket, it is the traveller who is compensated)
Ultimately if ticket prices go up because that’s the cost of having a somewhat reliable service that actually delivers on its promise I would not say it’s a bad thing. It makes the playing field even such that airlines can’t get away with undercutting service quality to compete on price.
You know which way that always goes.
