From discussion with a number of drone service providers, it seems to me the restrictiveness really depends on the context.
For things involving flying a drone over a crowded area, it's definitely hard to get authorization and we've seen projects being abandoned because of that. So yeah, drone delivery in cities might take some time before it is allowed.
On the other hand, most of the commercial applications I've seen are around using drones for mapping. So basically taking pictures and then processing them (create orthophotos, build a 3D model, detect objects, etc...). This usually doesn't involve flying over crowd and for a number of use cases (farms, construction site, security) the fly would be over a private property. A lot of people are able to do this without any legal restrictions.
From what I know of the history of the swiss Drone Valley, the two biggest success are sensefly [2] and Pix4D [3] and those are in the mapping business. Two of the booming startups would be wingtra [4] and flyability [5]. Wingtra seems to be mapping-oriented as well and Flyability develop drones that can fly inside. So a lot of the swiss drone valley is really into drones that can take pictures for mapping & inspection and I think this segment will continue to see massive growth in the future.
