We needed that (very good) video a few years ago when all new new 991 owners, and many first-time Porsche owners, were freaking out about their brakes.
I would have liked to been a fly on the wall in Stuttgart during these planning meeting:
"Hey guys, ve have a lot of 991 owners complaining about brake noise. What should ve do?"
"Let's make a video!"

Sorry, not buying it. Brakes on street cars should not make noise in normal operation.
Excuses and hand-waving are not what we pay these guys for. To the extent customers complain about brake squeal, it's an engineering problem like the tens of thousands of others that had to be solved before the car hit the showroom.

My '12 TTRS had moster brakes that squealed like greased pigs set on fire. I didn't mind too much. But, enough owners complained that Audi 'fixed' the problem.... by hanging 4 ~5 pound weights on the inside of the calipers to change the resonance. That's exactly what that nose-heavy beast needed: another ~15-20 pounds on the front axle.
Our Z06 has quiet brakes. They're not very good.
Brake system design involves trade-offs between performance, noise, dust, (low) cost, weight, effective temperature range, and longevity. You cannot maximize all of them.
Porsche has just-about-always put far more braking capacity into its cars on a pound-for-pound basis than most any other car maker. They can be used and abused way more that just about any other car non-ballers can buy. The downside is dust and occasional noise.
I would expect that one can find low-noise pads. Just expect that one or two other characteristics of the system will suffer (e.g. more expensive, more dust, less performance, lower service life, etc.)

I run pagid yellows which squeal like a freight truck most of the time, except for the 2weeks after a track event.
The answer to my wife is to go tracking every 2 weeks so the car is quiet.
takes about 2 weeks to wear off the transfer layer on the pads with cold brakes
