A Silicon Valley résumé is looking increasingly toxic in Washington — and that’s complicating President Joe Biden’s efforts to fill out his team to take on tech.

In the wake of the social media fueled riot on the Capitol, many on the progressive left have argued that Twitter and Facebook’s early reticence to restrict extremist content highlights the danger of the hands-off approach Washington, D.C., has taken to the tech industry for years.

“We’re seeing the detrimental effect of this unchecked power,” said Morgan Harper, a senior adviser with the progressive pressure group American Economic Liberties Project. “It’s endangering lives.”

It’s a stance shared by many on the party’s left-leaning flank, who argue social media companies allowed years of heightened levels of partisan vitriol that culminated in the Jan. 6 violence. And that’s on top of other criticism that had already been building against Silicon Valley, ranging from antitrust violations to the abuse of user data. It’s a very different environment from the Obama administration, when Silicon Valley executives were praised as innovative leaders and seen as key partners to the administration.

Tech industry critics are seizing on the moment, and ramping up the pressure on Biden to think twice before hiring tech industry veterans for the many still-unfilled administration roles that touch on tech. While they had unsuccessfully raised objections to some of Biden’s early picks, they are marshaling more forces to oppose choices that, they say, are deal breakers.
