Here's another theory - maybe it just doesn't make sense financially. A source-only netflix wouldn't fly. So, they would need to get developers, packagers, QA, and support for either one or multiple distributions and many different hardware configurations, not to mention dealing with linux's plethora of audio subsystems and graphics driver issues. It's possible to test on every ChromeOS device. It's much more expensive to QA and support every linux desktop configuration. Perhaps it's just not worth it because there are so few desktop linux users. The expected income would need to be much more than paying for linux devs/packagers/QA/support before it is a good business move.
