I came here 10 years ago specifically to open source as much as I could. While the first 7 or 8 years were difficult, recently it's become extremely easy to open source things at Microsoft. I would even say that things are now "open by default," which is huge compared to closed by default. We have people who used Macs as their main machine full time, as well as people who work exclusively in Linux. It's definitely a good time for open source in Microsoft.
