It's worth keeping in mind how extremely unfriendly to tech the last admin was. At this point, it's basically proven in court that emails of the form "please deboost person x or else" were send, and there's probably plenty more we don't know about.
Combine that with the troubles in Europe which Biden's administration was extremely unwilling to help with, the obstacles thrown in the way of major energy buildouts, which are needed for AI... one would have to be stupid to be a tech CEO and not simp for Trump.
Tech has been extremely Democratic for many years. The Democrats have utterly alienated tech, and now they reap the consequences.
What are you talking about via Europe? Holding tech companies accountable to meddling in domestic politics? Not allowing carte blanche to user data?
I understand (though do not like) large corps tiptoeing around Trump in order to manipulate him, it is due to fear. Not due to Trump having respectable values.
