I think the point is not difficulty but rather recklessness. I don't think other large players lack the ability or the deep pockets to do the same, but they might be lacking on the recklessness department for whatever reason. That reason, whatever it may be, might be the interesting part here.
No it's not. That statement assumes other corps care. They don't. If it was easy, everybody would be doing it. The fact that not everyone doing it is not because everyone else is not out of the goodness of their hearts
