You still haven't shown us why surge protectors and UPSs are bad, only that they can be ineffective, and you still haven't shown any evidence, only more theory. How did they prove the plug in protector bypassed the psu's internal protections? How do we know that the psu's internal protections weren't already faulty? What you are saying, while it could be 100% true, goes against the common knowledge of the masses. You need to provide more evidence to convince people of something that goes against what they were taught to believe for most of their lives. What the telcos do isn't proof.Explained is why all telco switching stations locate protectors as close as possible to earth ground. And why a protector is located as much as 50 meters away from electronics. Telco routinely do this because 100 years of knowledge demonstrates what is necessary for surge protection.
A 1994 IEEE paper also describes what happens. Dr Martzloff's very first conclusion describes how plug-in (point of connection) devices are harmful:
> Conclusion:
> 1) Quantitative measurements in the Upside-Down house clearly show objectionable difference in
> reference voltages. These occur even when or perhaps because, surge protective devices are present
> at the point of connection of appliances.
Long before Dr Martzloff's paper, we saw same. Two plug-in protectors connected the surge destrctively into two powered off computer motherboards. Incoming on AC mains. Through protectors (bypassing protection in each power supply). Outgoing via NICs. Through the network. Into a third powered off computer. Out to earth ground destructively via modem and the telephone line. Three times explained is why adjacent protectors are not used and can contribute to appliance damage.
Meanwhile, dimmers were using semiconductors (thyristors) since the 1960s. If hourly or daily surges are destroying electronics, then you are replacing dimmer switches daily. Those mytical surges do not exist despite a majority who believe otherwise. Why are you not replacing dimmer switches and clock radios? Because all electronics already contain protection that plug-in devices are supposed to provide. Some of the more robust protection must already exist in a power supply. But selling a supply that is missing these functions (and still boots the computer) means higher profits even at a lower retail price
Informed consumers worry about the rare and destructive transient that occurs typically once every seven years. A UPS does not even claim to protect from. That number can vary significantly even in the same town. Therefore informed consumers earth one 'whole house' protector. A solution that costs about $1 per protected appliance. That makes even direct lightning strikes irrelevant. That means everything is protected including furnace, refirgerator, and bathroom GFCIs. Which device most needs protection is a surge exists? Smoke detectors (or fire alarms). None must fail during a surge. The single effective solution also makes lesser transients irrelevant.
Protection is always about where energy dissipates. If permitted inside the building, then it will hunt for earth destructively via some appliance. The informed consumer earthing one 'whole house' protector so that energy is not inside the building.
US Air Force defines where protectors are best located. Not plug-in protectors. The US Air Force says:

Effective protection means energy is harmlessly absorbed in earth. Means protection already inside every minimally acceptable supply is not overwhelmed. A protector is only as effective as its earth ground. Therefore the effective protector is located typically 'less than 10 feet' to single point earth ground. And may cost tens or 100 times less money.
And again, I already said I never claimed surges are a daily occurrence, so you can drop the "mythical surges" routine, it's not winning you over any supporters either.
Oh, and fyi, that dimmer I referred to earlier? From the 50's. It was in my grandmother's home. It is older than my mother, and she was born in '58.
