Acronis has some pretty good (and quick) support, but they're Russian, so conversing is a bit hard.
I don't agree with this business model, either, and will be seriously reevaluating our next purchase for AV, Backup or other products. I can sort of see it, as Symantec is at the point where it's products should just work. The 4% of users with problems can probably tie it to something with their setup, and Symantec feels YOUR problems shouldn't become IT'S problems. But hey, that's the price of doing business, isn't it? Your analogy of the car is appropriate. Even if your car keeps breaking, at least you have someone to blow off steam at so that you'll feel better about your purchase. I know when I call these places that the chance of someone doing better troubleshooting that I've done is slim... but it's always nice to talk to someone.
And it sets my bosses at ease more when I can say, "I talked to the manufacturer and they don't know what's wrong," instead of "I've fully tested it, but haven't found a solution yet."
