I don't think you have been looking at Logitech keyboards for a while. Logitech Craft, which is a few years old retails at $169. MX Keys (which this is presumably the mechanical version of) costs $119
I don't think the MX or the Craft series are aimed at gamers, but at office workers / typists.
Logitech Gaming Keyboards, such as G413 TKL is $69 and the Pro K/DA, which is a collaboration with the League of Legends Band/mascots is $129
$150 for a logitech keyboard is in no way high for the brand, or an attempt at taking advantage of gamers.
I do agree, though, that they do take advantage via FOMO or perceived elitism, to a degree, with such pricing.
If you're doing CAD and you need to get a laptop with a decent GPU in it, the enterprise version of that will cost you twice as much as the gaming version.
