Unfortunately enlightenment / classically liberal values (different from leftist liberal values) have been on the decline in the US, particularly with younger generations. Free speech is one of those values under attack. Even the ACLU, under different leadership than in the past, is wavering on free speech (https://reason.com/2018/06/21/aclu-leaked-memo-free-speech/). James Kirchick spoke at length about this unfortunate evolution in a recent podcast (https://quillette.com/2021/04/09/podcast-144-james-kirchick-...).
The West (as nations, corporations, citizens, etc) is not in a position to proselytize on this front any longer. Although the US government is bound by the first amendment, we have effectively outsourced our right to free speech over to private monopolies that aggressively censor views that don’t fit progressive perspectives. Biden even recently said that no constitutional amendment is absolute, which seems like further normalization of erosion of fundamental rights.
With the floodgate of censorship already being opened in the West, it seems there is no one on the side of unfettered speech and intellectual freedom today. At the same time I understand why other nations are wary of both the power vested in social media and the influence of savvy or highly active participants therein. It’s a risk for local culture, politics, and stability to be undermined through that channel. Even European nations are increasingly skeptical of outside influences corrupting their sovereignty (https://www.nytimes.com/2021/02/09/world/europe/france-threa...).
