I've never been able to find anything definitive about Thiel and Ayyadurai. I did a longer search last year, but here are links I dug up just now. http://gizmodo.com/peter-thiel-wont-say-if-hes-bankrolling-l..., http://www.latimes.com/business/hiltzik/la-fi-hiltzik-email-....

That said, to my knowledge, Thiel has refused to publicly deny it. If SV had more scruples, he'd be forced to go on the record about it, because funding Ayyadurai would be indefensible.
