Lots of devs prefer Linux but are forced to used Windows by their employers. So both can be true at the same time.

The survey accounts for personal use as well. If this was the case, I'd expect the personal Linux use be higher than the professional use.

Used != Prefer

Even for personal use? If devs preferred Linux so much, I'd expect them to use it at least in their own time. But, what the stats say is that people use Win even more when it comes to personal devices, and Linux, not even a tenth of a percent. If anything, that looks like that dev don't prefer Linux. They use when the employer pushes it onto them, but not anywhere else.

The problem is that many games and software still only work on windows.

Is that why developers don't prefer Linux?
