While this is undoubtedly true, I still don't comprehend why.
The development workflow on linux is an order of magnitude better than on OSX. Package management is built into the distro, the directory structure is sane, LUKS is (probably) less likely to be backdoored by the NSA than FileVault, you can use keyboard-centric window managers, tiling window managers, etc, far more of the system is available/configurable via scripting or terminal, you don't get grey screens of death regularly, it doesn't send tons of telemetry back to the mothership, and you don't have to reset the PRAM and SMC every goddamn week just to get the thing to boot.
OSX is probably only a "good" comparative developer experience if you're forced to use XCode for something. Otherwise, it's a disaster.
