I disagree. There's different ways of solving techy-techy stuff. One is to have 2 or less mega-platforms (e.g. iPhone/Android is a duopoly, Google & Facebook are monopolies) that are barely compatible. The other is that the ecosystem is so open that competition is easy - e.g. email. The fears of some lawmakers about "if we break up US companies, then Chinese alternatives will take over" are misguided. This is pretty easy to prevent by (1) mandating compatibility (e.g. all social media must be open / federated, all phones must support all app frameworks) or (2) simply banning "rogue" companies (e.g. Chinese or in general those linked with security agencies and/or totalitarian regimes). In the long term, in particular (1) would IMO foster a lot of competition, and be hugely beneficial to consumers. In part because the market would be much more open - if some company wrongs you (sells/leaks your data?) you just move to another company.
