While i share your complaints about how distribution companies handle game releases nowadays, i think we have to be a bit honest with how the community at large operates as well.
I would probably have no problem waiting an extra 6 months to get a fully polished product and by the sound of it, it seems you share this opinion.
However, there's a large part of the community who's been chomping at the bit, going "is it ready yet?" and "how much longer?" all along the way.
I too dislike incomplete games but i know there is no such thing as a 100% complete and realistic simulator. The thing is, what happened with CoD was a choice of "scaled down release now" instead of "full fledged content half a year later".
I have no problem either way, because i can weigh pros and cons and if the "completeness index" is to my liking i can purchase, if not i can wait until more things are added (which is exactly what you describe, it's a perfectly valid outlook on things).
The stirring up usually comes from members of the community who on one hand want the game to ship early, but on the other hand don't realize that this will put a dent in things with regards to how complete it will be. I'm not referring to you here, it's obvious you realize this counter-balancing going on behind the scenes and i would expect no less from a member of the industry.
What i'm trying to say is that just like the features that make it into the release version are a compromise between time, cost, feasibility and hardware requirements, how to deal with the community and balance the desires, wishes and sometimes downright demands between different groups of fans with diverging agendas and priorities is also a tough balancing act
