No, it is true. You missed the "under 30s" qualifier. Facebook indeed remains incredibly popular in the 40+ category, which is dominant given demographics in most countries of the subset I mentioned: "youth speaks good English".

> Also, I don’t like the current US administration, but you cannot make the claim somehow China is better, especially to minorities.

Luckily I didn't make such a claim, instead just rejecting the premise that "The US has a global reputational advantage that will take decades to fall behind China, regardless of what any US administration does.". That global reputational advantage has been cratering with no signs of stopping, and is indeed on pace to run out long before "decades".
