I am reluctant to jump into this argument, but you keep making this claim and I think it is unfounded.
The only units which will be made available at 12 months to members who are not owners will be from owners who have elected to "donate" their usage to the Abound pool for that year instead of using it. So the effect on other owners is not different than if those owners had decided to use their home resort ownership that year. And I don't think you'd be complaining about owners choosing to use their ownership at their home resort. That's all that is happening here, except that they're allowing someone else to use it instead of using it themselves. The usage is exactly the same, just different bodies occupying the beds.
You might not like that for some reason, but it strikes me as 100% fair. As an owner, I can use my ownership almost any way I want to, including by allowing someone else to use it. That's all the Abound program does.
Now if MVC is taking more weeks than have been elected to the Abound pool and making those available to be reserved by non-owners, that would potentially be a problem, but we have no evidence that they will do that, and I think it's unlikely.
Also remember that MVW owns lots of weeks/VOIs, and those have usage rights too. They can do all the things with those VOIs that we can, including electing to put them in the Abound pool instead of using them. That also doesn't impact the rest of us. They were already using those VOIs in other ways, like renting them on Marriott.com, using them for Encore packages, maybe selling them to II, etc.
I feel like there is a lot of unnecessary angst here. But the proof, as they say, will be in the pudding, and the pudding's not yet been served.
