While it cannot be said that 41 is inferior to 10G, it is very true that having 41 in place of 10G will not benefit the PLAAF much. It is a relatively unfamiliar engine and will be extremely dependent on Russian parts and support, effectively negating any longevity advantages. Perhaps he meant WS-15 or simply referring to effectiveness of using AL-41 over WS-10G. Maybe he will explain.
Most of his post was in reference to how ridiculous the suggestion that J-10 is sporting a Su-35 TVC engine within two years of receiving Su-35. That would be record reverse engineering the Su-35 engine, changing it totally, applying it to a single engine frame that is totally different in layout, structure, dynamics to Su-35 and getting the FCS and pilot familiarity to a level where they are certain it can perform pretty demanding moves at a public airshow. This usually indicates at least a decade of work and ongoing testing, modifying, and training to get to this level. The article is quite clearly absolute BS since WS-10x TVC is based off WS-10 core and TVC nozzle operates differently to Su-35's and the petals are entirely different. He has a good point dismissing the article but the statement on superiority of WS-10G? Yeah that's one best left for the poster to explain.
The notion that the J-10 test bed is powered by Izd. 117S (or even contains technology derived from it - if Russia contributed it would have been Salyut rather than Saturn) is downright risible - that goes without saying. Nonetheless, you can discredit the article with factual information, there's no reason to counter with equally ridiculous claims.
Two wrongs don't make a right.
