I think there needs to be a law that forces companies that benefit from network effects to open their standards once they reach a certain market power (similar to antitrust and monopoly laws). For example, Twitter would be forced to open their standard and then anyone can build clients (and host servers), just like IMAP and POP3 works for email. I think this even will have a bigger effect than breaking up these companies, and it will be easier to push through politically. Edit: Typo
