So Amazon buying iRobot is a competition problem, according to Lina Khan. A Chinese company "Shenzhen PICEA" acquiring it, however, is apparently no issue at all.
This reflects a deeply misguided approach to antitrust enforcement, under Lina Khan.

@sung.kim.mw you'd have to elaborate... Amazon is already huge and probably has a significant market share as a sales channel for this type of product. The acquisition by PICEA is also vertical integration, but I would expect its position in the market (suppliers of motors for vacuum cleaners) is not as dominant or safe; suppliers typically have lower market power.
