Wow, that's a lot of postulation with blatant hero/villain syndrome being passed off for facts.
There's a good amount of truth to it though. Chris was pressured or told to write Legion a certain way. When he wrote "no data available" it was because he was in damage control mode. He even wrote a semi-plausible explanation for it. Unfortunately it was cut because he wrote too much ( the original Legion/Tali confrontation ).
However, while I'm no fan of Walter's writing, I don't think he can be blamed entirely for the destruction of the geth in 3. I got the impression from L'Etoile's posts that Casey Hudson was the one pushing the emotion business. Weekes didn't seem to have a strong grasp of the issues either. It's not so clear cut.
Animals certainly have sentiense as they feel, have emotions and suffer pain. Some also show singns of sapience. And how society develops 200 years from now is unclear. It is not for L'Etoille to decide.
There are two different kinds of AI in the MEU, top-down models and bottom-up models. EDI represents a top-down system deliberately designed by organics to achieve consciousness. Within the MEU these types of AI are commonly considered to be sapient.
The geth on the other hand are bottom-up models. They were never intended to become conscious or sapient by organics. L'Etoile certainly intended for them to be both. His job was to create the MEU. Insofar as I'm concerned it was his decision to make. However, your well within your right to disagree.
It should be pointed out that the geth never considered themselves to be slaves in the same sense that humans have. Geth choose to serve the quarians. The quarians were racist in that sense. They couldn't accept that geth would come to that conclusion because the quarians would have refused to serve had their positions been reversed. It's the basis for why geth don't understand organics. Sadly most players are as confused as the geth are. They never tell ME2 Legion to give back the quarian homeworld. They never ask it's opinion on doing dangerous work for the quarians. They don't listen to Legion's answer when they ask if peace is possible. They reject it's reality and substitute their own.
Side note! You all hurt Chris when you capitalize races incorrectly. The only ones that get the capital letter treatment are the Protheans and the Reapers. His name is also spelled L'Etoile. However, I don't think that bothers him nearly as much as the race capitalization
