Frankly I don't think there is single answer.

Already second most common reason to outage is software defect, SDN will
just reduce software MTBF and can potentially break lot really fast.
I don't want to run some HP OV SDNd magic black box process deciding what
happens to the network and I don't have the resources (or motivation) to
custom develop the software.

For researcher it seems really invaluable, you can test new protocols in
real equipment.

For GOOG/FB et.al. I can also see value, as I imagine their software stack
is already very specialized, very home-grown. SDN can allow them to tie in
network to their current VM/service orchestration tools, essentially making
sure network and services share synchronous view of what should happen.
