Hedqvist here. It is correct that the dispute in Sweden between Skatteverket and Skatterättsnämnden was regarding the fees. The person from Skatteverket responsible for the appeal made that very clear in a comment in a news article (in Swedish).

Roughly translated: "Our goal is not to add VAT to bitcoins, but there could possibly be VAT on the exchange fee".

BUT, in the last few days I have heard that there is an opinion among lawyers and other experts that "questions referred to the CJEU are formulated so broadly, that they could be interpreted as also pertaining to the sale of bitcoins as such". I don't have the expertise to have an opinion on that, but if that is true it sure makes the case even more important.
