Dear Tim,

I'm sure there will be an update of our write-up, considering all the 
feedback we received.

Concerning the "Open" issue:

I'm guilty of not always being clear about the destinction between LD 
and LOD. In fact I believe many people are not clear about it. We should 
ask why they are not. And in fact our little write-up exposes one 
probably reason: The notion simply is rather unclear. "Linked Open Data 
must have an open licence" is - in the light of the analysis in the 
paper - almost meaningless, as "openness" of licences is not a boolean. 
There are many shades to it, and most of these shades do not allow 
readily for commercialization.

Concerning the title issue:

I agree the choice of title is provocative and probably "unacademic". 
The colloquial language used in the paper is also "unacademic". However, 
as the main purpose of the write-up is to stimulate discussion on the 
topic - the title serves this purpose very well I think. However, I 
admit I rather like your laternative suggestions :)

Best Regards,

Pascal.

>> Abstract.
>> Linked Data (LD) has been an active research area for more than 6 years and many aspects about publishing, retrieving, linking, and cleaning Linked Data have been investigated. There seems to be a broad and general agreement that in principle LD datasets can be very useful for solving a wide variety of problems ranging from practical industrial analytics to highly specific research problems. Having these notions in mind, we started exploring the use of notable LD datasets such as DBpedia, Freebase, Geonames and others for a commercial application. However, it turns out that using these datasets in realistic settings is not always easy. Surprisingly, in many cases the underlying issues are not technical but legal barriers erected by the LD data publishers. In this paper we argue that these barriers are often not justified, detrimental to both data publishers and users, and are often built without much consideration of their consequences.
