Your shrugging is incredibly annoying and disingenuous and “soft power” is being used to weasel completely illegitimate claims. Does China like doing soft power with its pop culture exports (such as they exist) and even the mere existence of platforms like AliExpress? Sure. Does a platform run more by western than China represent a threat by the latter to subvert the US? Not without actual substantiation.

China’s interest in bilateralism is neither saintly nor even particularly based on being a Dictatorship of the Proletariat, but the fact that it knows that it wins by playing the long game and giving itself time to develop, while its main enemy is perhaps the most effectively pugnacious in world history (contrast with a state like the DPRK that talks a lot of shit but ultimately isn’t getting into any new wars, just staying in the one it was founded under). China is averse to fomenting revolt in the US or elsewhere because it wants to undercut power politics and play to its strengths rather than those of its enemy. To do that, it has a reputation to uphold that it won’t imperil with some hail mary tiktok brainwashing scheme that would certainly fail if it even had the power to pull it off (and, again, tiktok is already run by parties who don’t take orders from China).

The US isn’t doing this out of strategic interests against the platform inherently, it is doing it as some combination of a scapegoating kabuki theater and to pave the way for further protectionist policy by normalizing banning things just for being Chinese on a flimsy red scare pretext.

I think you’ve already had this quote paraphrased to you, but I didn’t see it properly rendered, so here’s the original:

Many westerners come to socialism not out of necessity, but out of disillusionment. We are raised with the idea that Liberal Democracy is the best system of political expression humanity has devised. When confronted with the reality of its shortcomings, rather than narrowly discard liberalism or electoralism, the western anti-capitalist tends to draw sweeping conclusions about the inadequacy of all existing systems. Curiously, though it would at first seem that such denunciations are more principled and severe, they are in fact more compatible with existing and widespread beliefs about the supremacy of the western system. That is to say, when a Marxist-Leninist asserts the superiority of existing socialist experiments, they are directly challenging the idea that westerners are at the forefront of political development. By contrast, the assertions from anarchists and social democrats that we need to build a more utopian future out of our current apex are compatible not only with each other, as discussed earlier, but also do not really offend bourgeois society at large. They in fact end up not sounding too different from the arch-imperialist Winston Churchill holding forth on how ours is the worst system, except for all the others which have been tried. Western chauvinists, consciously or unconsciously, struggle with the idea that they should study and humbly take lessons from the imperial periphery. It is much easier for the chauvinist, psychologically, to position oneself as at the very front of a new vanguard.
