* No Bluetooth support on OpenBSD at all, and it never worked on FreeBSD for me. Linux used to have issues with some devices, but it has gotten much, much better over the recent years (or devices have gotten better).
* Wifi on Linux mostly works out of the box nowadays (with the exception of some Broadcom chips, but even they are getting better). Completely different story on the BSDs, while they have decent support for some vendors like Intel, they take quite a while to support new hardware.
* Gaming is not really a thing on BSD.
* Container tech like Kubernetes and Flatpak does not work on the BSDs.
While Linux has taken a long time to catch up to Windows (and still isn't there yet in some areas), I feel like the BSDs lack the manpower or interest to even keep pace with the world around them. Not only are things not getting better, they are getting worse.
