That company is well known. Not meant in a rude manner. I would put some of it down to PR as you mention.
I would hazard a guess that people who take out aftermarket warranties (as highlighted by the comments above in fact) are buying expensive to maintain cars in the first place and want to defray the costs. Seems fair, Once a car model is 3-5 years old the frailties will become common knowledge so it is easier to sell against them. Manufacturers seem to see the repair and parts business as their main bread and butter until the recent chip shortage issue and milked it for all it is worth.
As second/third/fourth owners it makes a lot of sense to take one of those at the time of purchase. I did when I bought the S2 from an independent dealer. How that went is a different discussion. So the fact that Pork and all the others are in the list is not a great surprise. I was surprised Bentley was number 1 but they are complex monsters. I have a local dealer near me selling a beautiful DB9 with immaculate interior and exterior, 40k miles proven for £35k. Younger me would have gone for it with a decent sized warranty.
Looking back, the two main Porks I owned were both stripped out Club Sport 968's. I bought warranties with both, Pork for the first one and aftermarket for the other. They were rock solid and left a lasting impression of being made from thick steel. Neither warranty was ever claimed against. They were also pretty simple, including wind up windows and manual everything. The boot release was a plastic hoop poking out of a carpet hole on the drivers B pillar and was a simple cable back to the hatch mechanism. Loved it. I bought it based on the engine and handling from one short test drive. At first it felt a bit solid and spartan but after 6-9 months the dependable, trustworthy, aspect displaced that. I will also never forget the Recaro buckets, the Tillets in the Coupe are the nearest I have experienced since. Look rotten for comfort but actually keep you solid so you enjoy it more.
