It's like China is just that one country (aside from the Khmer Rouge) that every ML (aside from Dengists like us) agrees to hate on.
Fellow Traveler and leftypol uploaded videos criticizing them, the Shining Path hung up literal dogs to protest them, Maoists go all insane saying that it's some red fash social-imperialist nation because (insert nato propaganda here). And Hoxhaists claim that China was never socialist and that the only socialist nation ever was USSR before Khrushchev and almighty holy Albania.
What is it that makes China so controversial even among MLs? I get that it's not perfect and every AES state has their Ls, but jesus.
Personally, I see that as a sign the strategy is working. Using market forces to your advantage, as a nominally socialist organization, is inevitably going to draw a lot of criticism from your left. You get two groups: purists who see any sort of market action as an immediate and disqualifying sin; and more principled materialists who understand the rational, but also recognize the risk of being overwhelmed by market forces. It's nice to say you will strip out private capital in the future, but when will that actually be? When the conditions are right, will it actually happen? Worse, will your organization even be able to recognize those conditions? These are important questions, but we're not gonna see the answer any time soon.
In the mean time, western leftist doing the fire-&-brimstone preacher act is useful. Capitalists (the smarter, self-aware capitalist...) hear leftist discord over China and interpret that as meaning their oversees investments are safe.
