@Aucald Curse of flesh is only relevant to titan constructs. It has nothing to do with trolls and elves who develop from the life forms Freya seeds (although the elves get further developed by the Well of eternity possibly, the shape and make up likely guided by Elune), Quillboar, furbolg etc etc.
I would guess that the old gods probably notice organic beings are subject to their corruption, and use that as a means to both impair and even convert the titan constructs that successfully stopped them.
so it's not that flesh is evil, it was just a mechanism the old gods will use to weaken the constructs so they can take control of them. But the process also grants the constructs free will. Where did you get that from.. where does it specifically say the process grants the constructs freewill .. and is that to imply that the constructs don't have free will?
Stone beings seem to have free will though.
Also some of the keepers seem to get corrupted by Yogg-Saron anyway, and they're not flesh. I'm not entirely following. It doesn't seem that consistent. IS there another cause of the keeper's corruption that seems to work now when it didn't in the days of the black empire?
Also, can you successful prove that the constructs don't have free will.. so we must look at the Earthern of Northrend, the stone vrykul etc. Machines like M.O.T.H.E.R seem to work according to their programming.
Or are you saying sentience doesn't necessarily mean free will. i.e. the constructs can be sentient but are completely locked to mode of behaviour determined by their programming they can't deviate from. This ensures they cannot be corrupted. Keepers don't have that restriction with their high intelligence and morality, or they had the spirits of the titans in them , and it's only on losing that they became susceptible in Ulduar WotLK or they had total free will to begin with so in theory could be corrupted, they were just to wise/solid to be fooled by the old gods - so it took Yogg Saron much longer to eventually trick them. Such cannot happen with constructs because they don't have free will, but must work according to their parameters, but they can be re-programmed or reforged by the keepers with new instruction, which is what Loken is doing.
So while the curse of flesh on titans is one avenue used by the old god, the other is to turn the keepers too, and have them change the constructs.. Ofc, the old gods would try everything they can to get free. The whole plan of Deathwing, the Demon Soul, luring Sargeras, then using Azshara after that failed are all parts of the plans to achieve their end game of corrupting Azeroth.

That's unfair, the elves are only a side topic that came about because of their connection to trolls, sinnce we were examining trolls and how they come to be. It is also natural part of the discussion drifts to old gods, titan constructs, as it deals with how thigns are the way they are and distinguishes the different forms of life. . But don't let my strong opinions on elves derail this thread. Usually I mention something about it, someone responds only to disagree with the elf portion I stated. I respond to them to show my view on the whole thing and then they respond back on that.. and it seems that it's gone into an elf thread without meaning it to do so.

Indeed, it was a bit odd that the titan stuff looked like that. WE already have titan architecture in Ulduar, (and we see that night elven architecture from the ruins and place like Suramar/Zin'azshari are influenced by that, matching the lore of their enhanced intelligence and learning titan words and things).
However I notice that the titan giants in Uldir an other places in Zandalar have troll tusks, rather than the human looking appearances the keepers have. The same goes for those in Tol'vir. Whiles I can understand the felsh race building their own stuff around the complex, why/how does it influence Uldir guardians they certainly didn't build.
