This is discussed in the article. One of the points is that there is a chicken-and-egg issue with antitrust bills, where Schumer was refusing to table discussions because he claimed there was no support. So a clear demonstration of support, even in the other chamber, is a significant and newsworthy change in momentum. The other (related) point at the bottom is worth reading too. Basically the claim is that big-tech lobbyists were bragging about how they could stomp on even a small and common-sense procedural bill like this one. Instead they “stuck their necks out and got their heads chopped off”. That they had no good arguments and just ran a straight dirt campaign (on both D and R sides!) is a bad look that will be noted by the marginal Congressman.
