Social Media organizations like FB/Meta and Google have historically been some of the largest donors to the Dems, and their flip was a massive reason why 2024 went the way it did.
Vance has been consistently lobbying against the DSA over the past few weeks, and that's where his "free speech" argument is coming from.
I don't really care one way or the other, but I care about ensuring that large donors who flipped from D to R return to the D fold.
