Dean,
With due respect, your post CONFIRMS every one of my claims. Better units for owners vs. exchangers, Marriott rewards points (which IS a huge issue in my book), lower exchange fees for owners, lack of golf amenities for exchangers (huge in my book as that is a major factor in going the places we choose to go), and, if I am recalling my experiences correctly, in some cases, resort fees that are not charged to owners (I am fuzzy on where we ran into that, but we did). As to several other points you make, the point is that DVC is not doing things to exchangers that aren't being done in spades to DVC members at those outside resorts.
We may simply have to disagree. Your claim was "Marriott is NOTORIOUS for treating outside exchangers way different than owners both in terms of access to normal perks, access to villas, and fees." That is simply not true. I do think part of the confusion is that II does Marriott's internal trading while DVC does their own. There is not a single fee I can think of that an exchanger pays to Marriott for a given stay that an owner does not, not a single "normal perk" I can think of they treat members differently. They do give owners unit assignment preference, I don't see how anyone could argue with that when you do have to make a choice, DVC should do the same but do not. IMO it's significantly different to give owners preference, something that should be done within limits at all timeshares, vs withholding perks that cost nothing or almost nothing to the system. Most Marriott's give preference in the following order. Owners, then Marriott exchangers, then non Marriott exchangers; they also favor multiple week stays over single week stays. I can not think of another system that charges exchangers extra simply for the right of exchanging in. Some charge extra for AC or a fuel surcharge and my opinion would be the same as in this case, it's only appropriate if they charge both groups (owners and exchangers).
I take the fee part back (in part) in that Marriott requires all resorts to provide free parking to owners and members but the resorts can charge all others if they wish. The only one I can think of that does this is Beach Place Towers but there may be others.
If we accept your criticisms of Marriott, we also have to apply the same thinking to DVC. So if we assume a lower exchange fee is bad, DVC does the same but for all exchanges, not just internal exchanges. DVC doesn't charge members at all for internal exchanges. Same for ROFR, DVC is far more aggressive than anyone else save possibly Westgate. DVC also limits exchangers from the same local, Marriott does not. A DVC HH member can trade to a Marriott HH unit but not the reverse.
As for the fact that resale owners can't trade for Marriott reward points, that's true (in most cases). I guess it'd be the same as DVC not allowing resale purchasers to use
DCL, CC, DC and the like; it'd be doing the members a favor in my book. But one would know that going in and factor that in accordingly. Many timeshares limit perks by resale purchasers, that's one plus for DVC.
To be clear, DVC has the right to treat exchangers differently. My points are that the way they do it is petty, hurts members who look to exchange out, and doesn't help members that use their own resort in any way. And that members who exchange in should be treated more as members, at least in most areas, other than possibly Pool Hopping.
