1. It's less prone to warping
Ok, do you have any proof, documentation of tests, material data sheet etc ?
On the picture you can see that PLA have also warping syndrome:


2. It doesn’t require a heated platform.
It depends on the composition of the mixture, except that I think it’s a weak argument.
3. It does not emit toxic fumes.
Any proof? I talked to several laboratories that deal with testing material, and documentation is clear that everything depends on the composition of the mixture used to manufacture the material. You’d be surprised how many toxic contaminants is in your ecological PLA. Comparing the Z-ABS to PLA, the Z-ABS with a desire I can eat for breakfast instead of flakes with milk 
4. It comes from a renewable-source.
Again, any proof ? I think we should send some challange to guys from Mith Busters 
5. It is bio-degradable
Sure, this toxic PLA is bio-degradable. I’m not a EKO TERRORIST 
Summarizing:
1. Don't believe in everything you read on the internet
2. Don't copy the information for which there is no proof
3. Everyone can modifed any information on the Wikipedia etc. so after few hours I can change the information about PLA, write some informations about the fact that the PLA emits radiation, that contact with this material kills within 30 days, or causes reversible changes in body - DO YOU'LL BELIVE IN IT TOO ?
