Just when Microsoft thought they may have had Adobe appeased, it seems that the EU is doing it's own investigation on to whether or not Microsoft's recent actions violate anti-trust laws. On Wednesday, Jonathan Todd of the EU's “Competition Committee” said that they are in contact with Microsoft to find out more about how the next version of Windows and Office will handle PDFs, for both reading and writing. The biggest bone of contention that Adobe has is the potential for Microsoft to adopt PDF, then later “extend” PDF functionality, ultimately making Adobe's version of PDF “obsolete” or otherwise non-compliant with the latest Microsoft software. Microsoft has done before, so Adobe may have reasons for concern. All of this and more has led to Microsoft pulling PDF writing support from Office and turning read support into an option, but more may be yet to come.
