Johan, with all due respect - I have posted numerous magazines, TV broadcasts and websites covering the expedition. If you found precious little, it is only because you did not know where to look. The videos that I have shared are YouTube videos.
You forgot that Dutch ships were built shell first - very few frames were used to determine the actual shape at the start of a build.

This photograph shows only one full frame in position and if I were to guess, probably seven or 8 main futtock frames at the start of the build of the WB replica.

From the actual drawings of De Weerdt. Six full frames, and a further four futtocks and you have a hull. 20 Frames and large portions of the keel are more than enough to gain a reasonably accurate picture of what the hull looked like.
Of course, there is going to be a difference in the communiques distributed to the general press and those to the actual government departments involved in the research.
Also, the Russians are under no obligation to anyone to be "open" about their discoveries - why should they? We have to get realistic here about how things work in the real world. What have the Dutch done to find out more about these findings and discoveries. In fact, I will go one step further, Are they even aware of these discoveries?
And as to not being "open" about things - Are we really expected to believe that Barentsz's journal was lost when German researcher and commentator, Hessel Geritz has published and commented on portions of it? Are we really expected to believe that when the names of the ships of the 1594 and 1695 expeditions were meticulously recorded, that there is no evidence as to the identity of the ships of the 1596 expedition? So, if the Russians aren't "open" about their findings, neither are the Dutch "open" about their historical records.
