This is evidently false, since everyone knows the West Coast's political biases and everyone uses its tech products anyway.
It doesn't mean that there's no hate for tech companies and the Silicon Valley... Just go read what Fox News commenters and Donald Trump supporters have to say about Amazon, Facebook, Google, Twitter, ... sometimes justified (Bezos owning the WaPo, Eric Schmidt being quite cozy with the DNC), sometimes just on the basis of a perceived liberal bias (e.g Google/YouTube often accused of unsubscribing people from conservative channels or hiding search results without any concrete proof).
Complain about it, yes, but actually change their behavior because of it? no. Same with tech products.
Is there another option? Simply... not?
The equivalent could be a right-leaning silicon valley in middle america making competing goods and services. I see firms like this from time to time (often veteran owned), but it's a bit surprising it hasn't cropped up more. If Thiel etc were really trying to play the long game and erode the cultural monopoly of the coastal elite, creating competing centers of competence seems like a good place to invest.
"turn against them" !== "stop using their products"
