Maybe I’m missing something, but it seems to me once Democrats realize that they are literally trying to legally require Facebook rebuild the API that resulted in the Cambridge Analytica scandal they have railed against for years this bill will get dropped for dumb political reasons.
Opening up these services like this seems to be one of several prerequisites to preventing great harms, but doing so would be in conflict with a number of expedient political issues the parties have dug in on around platform censorship, data privacy, etc.
