Depends. It's not just efficiency, it's cost savings. If someone is running a large enough operation to save millions of dollars a year in cooling by using CFCs (assuming they're actually cheaper), and one is in a, um, lightly regulated industry (like Bitcoin mining) that uses massive power... well, that's a lot of justification. Small savings become big savings at scale.
