But you claim that only legislation can force behavior, and I'm pretty sure that if a few senators just relayed their frustration with broken screen time reporting to Tim Cook personally we could get some results.
Calls don't have enforcement mechanisms/consequences needed to ensure compliance with the desired outcome. The whole point of government is not to ask nicely that something be done, it is to use the power of the state to ensure that something is done. Assuming that the state decides to actually enforce its laws, but that is an entirely different conversation.
