The problem is the direction they will tend to head. Politicians see a centralized power center and think "we need to control that", and so will just create laws aimed at reforming the centralized service rather than breaking it up.

While what we really need is API access, data portability, privacy ala GDPR, and other laws that will foster competition between services, to straight up end their current playbook of creating mini-monopolies via Metcalfe's law. The standard tech-literate workflow to interact with Twitter should involve a third party client that abstracts over all such publishing services, and not defaulting to Twitter's proprietary web/mobile apps.
