"IPI Says Cartoonist Arrested in Vienna over Poster Carrying Image of President Putin" - But what position does IPI take on the arrest?

This report, if accurate - based on unnamed "information provided to the" IPI - seems to take no position on what appears to be a gross restriction on free expression by police in Vienna. I wonder if the hesitancy to protest - or so it seems - might have something to do with the undisclosed but rumored financial relationship/support between IPI and the City of Vienna? This would be an excellent time to disclose the details of all money and privileges extended to IPI because of its headquarters location in Vienna.
