We judge him for how and why he pitches in, bearing in mind that a Trump presidency is something he wanted to actualise rather than mitigate the effects of.

I don't doubt Thiel is capable and accomplished, but I also don't doubt he's ruthless, ambitious and tends to see things in black and white. It remains to be seen which of the ideas he's championed on he chooses to focuses his efforts on, of course, whether that's encouraging the government to support breakthrough research and entrepreneurship, slashing higher education funding and creating new tax shelters for the ultra rich, or just ensuring Palantir is well-positioned for contracts on new surveillance systems. Of course, reasonable people will still probably argue over what his contribution has been after he's made it. :)
