In the EBM embedded survey 2013, regarding microcontorllers[1], they asked the question "why did you use the same processor", pg 56:

Many of the reasons we're regarding software, indicating that software lock-in is a significant factor.

[1]they called it microprocessors , but pages 54, 60 hint we're talking about mcu's.

Assuming there was a bit of standardisation around the basic API. There is still significant lock-in by other factors.

It could be that the software is the thing they think first, if you ask the people writing it.

Maybe. But you have to consider that such surveys(and similar tools) could make semi company managers believe that software lock-in is important, and that's all it takes.
