You can only explain this by corruption. I think three letter agencies slept on that one...

Edit: Not sure why accusation of corruption is downvoted? It's a very difficult crime to prove and requires resources to pursue, so there is no appetite to prosecute. Big companies and civil service know that. If these companies pay off developers, they would have no reason to pay anyone else in their way and that would unlikely result in any consequences.
