Your link is listing half-truths. The WHO did order a test battery to check if frequencies in the 0-300GHz spectrum are harmful to health in any way, that much is correct. "Environmental Health" forgets to mention that the results were negative - no negative health effects were found.

The difference between holding a controller and sticking your head in a microwave is fairly obvious - about 800W of a difference. Apples and oranges.
You also don't seem to understand how a microwave works either - the principle is that whatever you cook in it is hit with strong microwave emissions, which excites the water molecules within the meal. The increased movement of those molecules is what creates the heat, not the radiation - it's not a nuclear reactor. "The frequency" doesn't matter, although it was picked specifically because it is safe.

If you were blasted with 800-1000W of energy in
any form, you would feel it too.
So yeah, stop believing and propagating bunk science. Don't expect the world to adhere to your silly requirements.
I will give you an amazing tip though, because I am generous. The antennas on both the PS4 and the Xbox One are removable - unclip them and your problem is solved. WiFi follows the inverse square law, the increased distance with no antenna to direct the signal will dissipate it into nothing. Next, buy a USB controller with no wireless capabilities whatsoever - they're cheap. Problem solved, you're no longer "holding a microwave". You're still wrong, but I wish you well.
