“This means he or she can monitor or access any data on private or public networks without regard to privacy laws.”

I think that Aquino has misinterpreted that section. It says “concerning such networks” and not “on such networks”. What the feds would have is the power to demand that any network deemed “critical infrastructure”, the definition of which is so broad as to be whatever the president says, must bare all of their network architecture to the government. There are many potential problems with that and while it could provide the backdoor to eavesdropping and shutdown, it is not in and of itself either of those. There are all sorts of real reasons to oppose that section, but I think Aquino starts from a false premise.
