That is not true, we have very detailed arial ortho images in Austria…
here for example for Upper Austria (one of the 9 federal states):

The problem is, in Austria the data is handled by the 9 individual federal states. Therefore it is not that easy for a third party to obtain the data.
The orthos provided in MSFS (and therefore in Bing) aswell as the orthos in Google maps are very outdated and poor - the data although exists. Our maps in Austria are usually updated every 2 months.
The other Problem is: the orthos before the WU6 were not ideal, that is true, but in many regions of the country far better as they are after WU6
