It's not often that the benefits QubesOS brings are what security companies (or the community) needs. If you do malware analysis, Windows VMs in isolation on a throw-away laptop is better. If you do penetration testing, Windows or regular Linux will be better, too. If you do extremely sensitive communication you're in a very niche group of people and chances are you're using a provided equipment by your superior (e.g., modified laptops).
