I suspect that as the value a company provides is more than its code, then increasing code churn does not lead to an equivalent increase in revenue. Even for a tech company, a business' concept, connections, knowledge, assets, non-coding staff, etc.. are a significant value and increasing code doesn't increase the throughput of that value. For non-tech companies code is the grease in the gears, not the gears themselves.
They are catching up fast!
