I mean, he has a point. It's clear U.S. tech companies have become hugely susceptible to hiring foreign spies and the issue of foreign governments stealing IP is real. There was a very recent public case of Apple's autonomous driving unit stopping a Chinese engineer from leaving the country just as he was bound for China after detecting he had uploaded a bunch of code to a personal account. And most likely many more…
2. Where did Thiel make this point? Thiel does not make the point that the Chinese are stealing US IP. He makes the charged point that Google executives (and somehow not Facebook executives) are Chinese agents. To that claim, I don't think he "has a point".
It's in very bad taste to me that Thiel would point this out, and claim the Valley "is getting a little bit of a bad conscience" when he sits on the board of the biggest troublemaker.
When Google leaks the personal data of millions of Americans, then maybe should Thiel start throwing stones.
