People do make choices to support companies that hold their values, sometimes at a personal cost. You may pay more for an item made under ethical practices with respect to people, animals, or the environment. You may even simply choose it because you like their attitude.
The Penzey's spice company, for example, does quite well despite deliberately excluding anyone who would be offended by their motto "season liberally". (The double entendre is deliberate.) But they also make a very good product.
So... Did these guys even achieve a conservative political end? Or were they simply hoping to get customers by pandering and deliver subpar service?
That's a pretty extreme accusation. Can you be more specific on why and/or how Thiel wants to get us back to feudalism? Are you just guessing based on investments he has made or has he actually said that? What are some examples of sick totalitarian ideas that he has for humanity?
I think he is more like a buzzword generator trying to destroy our democratic institutions for fun. I think he plans to become a warlord, prophet, king or something equally stupid in the climate chaos, though he is already 54, so we have that going for us. He plans to live forever, because buzzwords, but that's not going to happen. I don't think he would do well without his wealth either, he is not that charismatic or smart. He only meant to thrive on exploiting our world, he is the very product of our late-stage capitalism. His contrarianism is the antithesis of the rationalism and humanism that brought much of the advancements we enjoy today regarding human dignity, rights, ethics and laws, even politics. We don't enjoy them universally, and we won't enjoy them continually, but that's no reason to give up on them.
