Still do to a certain extent, but another way to look at this stuff, is that if you are using a Red on a job, you are probably on the sort of production where costs are running many thousands a day.
Lemo as opposed to something cheap (and the Lemo connectors are good) pays for itself very, very quickly the first time someone steps on one and it survives, hell probably avoiding loosing ONE take pays for that cable.
Also, frankly in the broadcast market they are pretty much the go to connector for low voltage, so everyone is familiar (4 Pin XLR is the other option, but there are rather too many variant wiring schemes for that, maybe 4 pin highrose but that is mainly a field recordist thing).
Rather like that battery pack for the Nagra that everyone on youtube got bent out of shape about (But that nobody actually in the industry was surprised, or bothered by), this is just pricing the way this market expects (The custom variant is a little annoying however).
$35 or so for the connectors plus wire, times three or four to the factory gate, plus 100% for the distribution chain, $250 looks about right to me for a low volume accessory at list.
Also, don't forget that nobody in this game pays list price....
