What are you suggesting? If a company is branded "Silicon Valley" it should no longer be allowed to make their own content decisions? If not them, then *who will make those decisions for them?*
A political government board? Talk about scary.
Obviously, the American political system is not in an ideal state (to put it mildly), but at least the sweeping bureaucratic inefficiencies make it hard enough to really change the temperature of the water by more than a few degrees in either direction.
"Silicon Valley" is just shorthand for "massive tech monopolies that have an outsized, inescapable, and pervasive influence on the way that every living person goes about their daily business"; and when you have amoral, profit-driven corporations that can "move fast and break things" - who are incentivized to wield their influence in whatever way serves their immediate interests - the human condition be damned, well... you end up where we are, here, now.
I am suggesting that we are not prepared to regulate companies like FAANG & Friends in a way that keeps them from remaking humanity in their own image as a means to their own ends. I am suggesting that it is horrifying that privately-held companies without any incentive to be responsible for the consequences of their actions against humanity, writ large, are able to effect social policy so much.
