http://hamapa.co.il (update the OSM Map / reuse their generated data)

I just saw the website of hamapa.co.il what I still think is a very nice project.
And I’m asking myself two things:

Why is their Openstreetmap data that old?
In their version Ashdod is barely mapped. They really need to update their data asap.

Is their any chance that we will get a approval to use their data in OSM?
I mean you can easily see the name and even housenumber in their popup windows.

Had somebody ever contact to them?
(Edit : Send them a email pointing on this thread.)

I also noticed that their tiles have right-to-left fixed
It means that they must have generated the tiles by themselves
