Worth pointing out, this specific kind of attack targets a device based on its mac address and sends it shedloads of junk requests. There is no chance of it interfering with emergency wireless transmissions.
That said, i agree it’s not OK to mess with other people’s devices like this.
On your link there, I’m sorry to say the author is making a very silly argument. It boils down to ‘if you see a specific race in this racist caricature then you’re the real racist’. This would only be true if racist caricatures were a new thing never seen before. It’s akin to saying ‘oh i didn’t mean black people when i screamed the n- word. You’re the racist for thinking the n- word refers to black people’.
That’s an extreme example but you see my point that there’s a history that’s being ignored.
