As a software engineer, I can tell you the integration people love is exactly what breakup proposals would destroy. Google Maps works inside search, Gmail, and Calendar because one company builds all of them. The Justice Department wants to force Google to sell Chrome, but Chrome's open-source foundation underpins most rival browsers too, including Edge and Brave. Break that apart and you do not get five healthy competitors. You get licensing fights, broken features, and a worse product for the two billion people who use it. The 2020 House report documented real harms, but structural breakup is the bluntest possible tool. Targeted rules on self-preferencing would fix the abuse without dynamiting products that work.
