We checked in with activists watching Biden’s antitrust moves carefully, and they see Wu’s return to the White House as signaling one of two possibilities:

1) Biden is building momentum for an administration that is tough on tech and will fill more crucial positions with policymakers in line with Wu’s views.

2) It’s a bone to the left before Biden picks more industry-friendly officials in those other jobs.

The bigger test will come when Biden fills the FTC slots and chooses an assistant A.G. for antitrust, who, among other things, will help decide whether the Justice Department continues its case against Google.
