Re: Contempt for users
Not to argue with any of the above (it sounds awful) but remote IR did indeed used to use a handful of carrier frequencies like 36/38/40/56 KHz which are at least in theory indeed incompatible on a hardware level with each other. Practically of course the receivers with the most ubiquitous 38 KHz typically received the neighbouring other two more or less just fine, but that's a different story...
