There's also the entire argument that Thiel doesn't really support Donald Trump, and that this donation is more of a strategic move that is coherent with increasing Ted Cruz's chances of election in 2020. Cruz got as close to a public denouncement of Trump as possible, and he will probably need the support of many of his voters (who knows if they'll even remember, doubt it) to be able to secure a victory. Thiel could perhaps be the trump card necessary as support, as he double counts as both a gay man and someone who remained "loyal" to Trump. I think that Thiel's opinions on how the world should look are more in line with Cruz's, and he himself has called Cruz "very smart". I don't know a lot about politics or Peter Thiel, but to think that a former chess champion and fairly renowned silicon Valley figurehead legitimately supports Trump is a little outlandish. The odds of there being an ulterior motive are far greater than the opposite. Not to mention that he probably saw all the negative PR coming, as well as the resulting dissociations. He probably believes it was all worth it.
