Talking about only a handful have more or less up to date source in full format. I can guarantee you that this was really not expected to happen. I am also very sure that if we would have had at least a small glimpse of what was going to happen and the servers open, then everyone would have dumped whatever was available at that given moment.

But to answer the last question, it's not technically doable for mr XY to leak personally the code announcing it on a forum, for example. I see more a leak elsewhere on torrent e.g.
Lawsuits are unwanted as you can imagine the value of the code itself.

Anyways, I agree that it would be great to make use of all that code that has been developed in the last 3-4 years in Finland.
