Lower cost, and some people are really attached to it because it's easier to repair pins if they get bent. You can straighten out PGA pins with a razor blade or a mechanical pencil pretty easily, LGA pins are... "challenging". It can be done but it's not easy.

(also, to be blunt, AMD processors undergo such extreme depreciation that they're practically disposable. After two years, AMD's flagship 1800X processor has lost 2/3 of its value, a nice high-end mobo like a C6H is literally more valuable than the flagship processor you had put on it. So it makes sense to have the processor be the one with the easy-to-damage sacrificial part on it. Intel it's the other way around, the processors are expensive and your mobo is probably the cheaper part to replace if needed.)

WOW you aren't kidding. First gen Threadrippers are cheap now.

I've seen the 1950X as low as $450 at Microcenter. TR4 motherboards are quite expensive, but right now the Taichi is around $260 after rebate at Newegg. Note that not all of the motherboards are designed to handle the higher-TDP 2970WX/2990WX, if you think that's an upgrade you'd make then look for one with a beefier VRM. Also, the cheaper ones lack 10 GbE or some other higher-end features.

You can also find the 1700 as low as $130 if you watch around. Needless to say, if you have any batch-processing type tasks that don't need AVX2, that's a hell of a deal too.
