Lina Khan was in power for years and didn't do anything about this.

Closest thing was a case where she blocked Sanderson Farms from being acquired but that was poultry.

She was starting to concentrate on the Ag consolidation [0] but my interpretation is she targeted tech first due to the industry's somewhat weaker political position in both admins.

She also didn't touch Comcast - and they are the kingmakers in PA and DE.
