This isn’t the first attempt the government has made to try and curb the power of Big Tech.
Tech stocks plunged this morning after an important announcement. The news? Big Tech may be facing some severe regulation as an antitrust bill continues to garner support. The American Innovation and Choice Online Act first received bipartisan approval from the Senate Judiciary Committee in January. Now, a letter has revealed it has the backing of the Department of Justice (DOJ).
As the Wall Street Journal reports, this development represents “the Biden administration’s first full-throated support of the antitrust measure.” This is no small thing. If the bill passes, it could severely limit the power of many of tech’s biggest names, stopping companies from favoring their own products over the products of competitors.
