I was talking in terms of IoT devices using these chips - more of them are likely to be on home networks, using WPA2 Personal than in offices using the enterprise version. For offices, wired smart devices or higher end wireless devices are more common, which tend to use custom silicon, rather than COTS modules like the ESP ones. Hue bulbs, for example, don't use ESP derived chips (if only because they need Zigbee rather than WiFi), and not does Lutron kit (z-wave), although Lifx bulbs do.
