I've read an article making that exact point. I've tried finding it but no luck. Essentially point was that Lego was scared of building/allowing a game that allowed "free blocks" as their whole business was selling blocks for money. It seems very short sighted but as any legacy business they tend to fall into that trap. This is why they allowed various games that utilize block as a art style, but there were not many building games.
