This would require a level of vision & planning we're not likely to see from political leaders, but I agree this is the best take here. If the goal of antitrust action is to keep the free market competitive, I think a better way to achieve this than enforcing a breakup of big companies is by legally requiring standards for open protocols that allow for competitors to interface with each other and compete on their service quality rather than their network size. How this would be done is a hard question without an easy answer. But breaking apart Facebook from Whatsapp isn't going to make it any easier for a new social network or a new messaging app to break into the space. Typically new social products can only enter a saturated market by targeting a niche and then expanding (e.g. Signal on a privacy/security focus or Discord on a gaming focus). Enforcing some level of open protocol makes it possible to try a new product without customers giving up because "oh but my friends aren't on here"
