Use any number of other communication methods or services that brilliant humans have invented to allow us all to talk to each other within seconds?
How have we reached such technical ineptitude that we can no longer consider other options other than big tech platforms when communicating? As if folks weren't stringing wires up across countries 100+ years before so we could send beeps at each other. Now we're going to write laws so your crazy relatives can talk about their conspiratorial alternate reality because losing their friends list is such a painful burden? I think I'd swallow a bullet before being asked to work on any technical features for this act. I know that's absolutely going to suck and I can't think of a worse place to end up after dealing with the difficulty of learning CompSci and programming.
This is going to be a waste of everyone's time and resources for no good social benefit. Literally go fix a bridge with this time and money and it'll do more good for the world.
