SV, and California as an extension of that, has never been as liberal as people say it is. It has always been about money. Any "social justice" messaging a lot of tech companies professed was all a poker play in the current zeitgeist around the time. It has died down quite considerably because they see the direction the country is going--they would rather have a president that espouses populism without actually following through on most of their promises.
Were there any other major Silicon Valley companies or executives that were pro-Trump other than Elon Musk and X? The whole premise of this post seems untrue on its face.
I read an interesting article recently about Thiel's, Musk's and Sacks' common career paths, views and ambitions.
One point that stuck out for me was how all three of them had spent a significant part of their childhood in Apartheid-era South Africa, as part of the white ruling class (so learned of Apartheid as a good thing or even had family that belonged to the ruling class). This is well-known for Musk, but I think less so for Thiel and Sacks.
Seems to me that gives their ultra-libertarian, "anti-woke", pro-inequality views another context.
Those with power want deregulation, those without want regulations that constrain those with power. Just so we're on the same page, those with power is corporate America, those without is everyone else.
That's a difficult question to an answer. The employees of those companies were most if not entirely anti-Trump, so, if the CEO was pro Trump, then they may not have want to say anything in fear of upsetting the employees.
