> Surprisingly almost two-thirds of respondents selected Linux as their development environment OS. Please note, for this question we allowed multiple answers. We’re not drawing primary OS popularity conclusions here.

What makes that surprising? A past result? A preconceived idea?

The surveys 9th takeaway is the same:

> Surprisingly, almost two-thirds of Python developers choose Linux as their development environment OS.

There's no answer here. I have no idea why the result is surprising: it fits what I would expect.
