Because the market is not a perfectly efficient discriminator of quality. In a more extreme way, why do homeopathic products exist?
The real question here is whether customer satisfaction is a fully sufficient criterion to determine whether or not something is a "ripoff".
For medical goods the answer is a fairly universal "no". For everything else it's more controversial. Is it correct to shortchange your customers as long as they don't know about it and are happy with their purchase? Are Bose's products actually shortchanging their customers, or is it simply satisfying a different set of priorities?
I don't think we'll ever come to anything resembling consensus on the above.
