No disagreement that forcing everyone into one closed commercially owned ecosystem would be a very bad thing. But I do wish there were more open standards that allowed universal methods of securely conveying information to and engaging in transactions with other specific people - email is really the only such standard currently and it's obviously not fit for purpose (certainly not on the "securely" part). It would still leave room for competition/choice between actual apps or service providers used, even if it's true the browser market is effectively a duopoly now.
