This entirely depends on your use case. For many gamers, Windows PCs can't be replaced by a Mac, let alone Linux. Hopefully Proton/Wine will bridge that gap and maybe even be ported to FreeBSD.

There are lots of servers running Linux that could very well be switched to FreeBSD, and lots more that are locked into Linux due to the state of hardware drivers or the containers they're running.

If all you're doing on Linux is browsing the web and opening terminals, you could probably switch to FreeBSD without too much disruption.
