Our politics may be profoundly polarized at the moment, with the nation’s two major parties at loggerheads over basic questions of democracy and reality itself. But there’s at least one area where Democrats and Republicans are in accord, and it seems to have major tech leaders deeply concerned.

Lawmakers are currently considering six bipartisan bills that would dramatically reform America’s antitrust laws and slap far more stringent regulations on major Silicon Valley firms like Apple, Amazon, Facebook, and Google, whose power has grown largely unchecked for years. It’s not clear which of the bills, if any, will pass in their current form. But, as Ars Technica pointed out last week, the fact that the efforts have the backing of both parties likely means that something to rein in Big Tech is coming down the pike. “Right now, unregulated tech monopolies have too much power over our economy,” Democratic Representative David Cicilline, who introduced one of the bills, told the outlet. “Our agenda will level the playing field and ensure the wealthiest, most powerful tech monopolies play by the same rules as the rest of us.”

With the groundswell growing on Capitol Hill, Big Tech is going to the mat, enlisting lobbyists, tech executives, and every other means at their disposal in a full-court press to stop the bills. According to the New York Times, that has included a personal call from Apple CEO Tim Cook to House Speaker Nancy Pelosi in early June to try to convince her that the legislation is “rushed,” anti-innovation, and harmful to consumers. (Pelosi apparently “pushed back,” asking Cook to identify “specific policy objections to the measures,” people familiar with the exchange told the Times.) “In a way I’ve never seen before, they are fighting tooth and nail,” Gigi Sohn, a distinguished fellow at Georgetown University’s Institute for Technology Law and Policy, told the Times. “They consider these bills existential for them because they get at their business models.”
