The issue is that it’s not that people express do not want the option, it’s just that if it is cheaper, they might go without.

In other products I’ve been involved with, the dilemma crops up. 90% of our customers pay for a premium feature, or else the feature has become so cheap it hardly saves us anything, we decide “guess everybody gets the feature”.

The argument that I might be willing to accept is when a feature carries a very large development expense, and you want to defray the cost among those that demanded it, both as a different model for funding the development and for keeping track of waning interest to discontinue that effort. Related are things like patent royalties and licensing fees.

However, we are taking about some resistive heating elements in a chair, hardly an engineering marvel and not really subject to a limited set of demanding supplier nor an area to run afoul of active patents. Once safety regulations got to the point where manufacturers had to run wiring to the seats anyway for the airbag modules, the hearing elements become negligible cost. A lot of budget models even shrugged and just tossed the feature in at that point. In that context, is crazy that a premium brand would think to pull such an obnoxious move.
