I can't really share the negativity towards rapha.
What they're offering is good: forgetting cost/value for money for a moment, their clothes are good quality - stylish, and work well, and their randonnees, will undoubtedly be very enjoyable for those who go on them.
The fact that they charge a lot for it is simply a consequence of the fact that there are people willing to pay that for what they are offering. They aren't making a profit because they are evil, they are making a profit because that is what the market will bear.
FWIW, I don't think they have actually even claimed that these are 'audaxes'. Randonnee isn't entirely synonymous with audax, is it?
