Faculty have responsibility for curriculum.
I offer all my courses with an online option now but the course itself as not changed any more than it would normally be changed. I don't depend on techies but if i did, i don't see why it would not still be 'my' course. Improving curriculum is part of the everyday job of faculty. I think you are confusing curriculum with how the content is managed or a good learning environment is created. For those specifically hired after a college has made a decision to go online, and the job description reflects this, this sounds quite reasonable an expectation to me.
