I am not seeing where this story has scandalous legs, the information was found out and the reporters who cover the Swedish Royal Family filed stories on it and/or did commentary about it.
I don't think that the Swedish Royal Family, nor other royal families, are quick responders to news stories other than noncommittal comments by the press office, so it would be odd for Sofia to do some kind of press conference specifically about this matter at this time since it does not seem to be anything more than the royal story du jour. However it probably will be added to the things about Sofia that are talked about on blogs and message boards going forward so I doubt if it will be forgotten, and there may be more "there there" once the business is up and running and we see what kind of activities are undertaken and the income generated.
Using Carl Philip and Madeleine as examples, they both got negative press and did not respond to each and every story, but at some point they did interviews and I would not be surprised if at some point Sofia does a sit down interview and gets asked about hot topics on the interwebs but I am not yet seeing that this particular matter has become some great big scandal in the Swedish media, at least based what's come across my cyber-desk.
