I feel like everyone is getting a bit carried away with this.
If a true threat to Section 230 comes about, the pushback from big tech would be tremendous. Not just Facebook and Twitter, but Google, Amazon, Apple, Netflix, big store chains like Walmart, Target, and various other companies will fight it like they always do. On top of that, there are so many politicians in big tech's pockets that this whole thing will probably never get its legs.
The fact that we have already seen the government push forward without caring about Trump's veto shows they aren't too worried about it.
Also keep this in mind, if we go by this year's session calendar for The House and Senate, The House goes on recess by the 11th and the senate goes on recess by the 18th.
And if we go by how things went at the beginning of this year, The House will be off recess starting on January 7th and The Senate won't be in session until February 3rd.
This means that at best, Trump has just two weeks to get a bipartisan bill through The Senate that doesn't reform 230, but kills it in its entirety. After that, it doesn't matter. By January 20th Trump is gone.
Should Biden get into office (most likely will) he has shared his opinions on 230, but hasn't shown much initiative in doing literally anything about it before.
And if Trump does veto, a reformed bill will not see his desk before the recess. And upon Biden taking office, the first thing he will do is sign the bill that Trump wouldn't; which kills the 230 hostage situation.
Does this mean there will be no attacks on 230 after this? Absolutely not. But it will always be met with enough opposition to delay and stalemate the movement as it always has.
This isn't new, 230 was challenged in the 90s as well and look where we are almost 30 years later.
Just keep in mind, Biden isn't on Twitter enough to give a shit about it and there are way bigger fish to fry in the first year of his presidency alone that we will be fine for the forseeable future.
So for the sake of everyone's sanity, think of it like this: we just need to make it 14 more days. If something happens in those 14 days, freak out. But until then, its business as usual
Edit: Also keep weekends in mind with The House and The Senate. They don't do shit over the weekend except get bills ready. So realistically, it's not 14 days; it's 10 days.
