If someone wants it softer then they are free to change the setup to their liking.

Early versions of RFTs were harsh, IMO. More recent iterations have been quite acceptable in terms of harshness, due to the tuning that BMW and other manufacturers did on spring rates, shocks, bushings, etc. While the suspension wasn't necessarily designed only for the RFTs, it was certainly optimized for the RFTs. That isn't to say that non-RFTs won't perform just fine, but let's at least give BMW credit for the work they did. It simply isn't all BS as is being claimed.
