I don't feel comfortable enough to claim knowledge of Disney's intent regarding any marketing benefit of fee subsidization. I do have to wonder if the vast majority of DVC purchasers (who have no idea of resales, dues increase data or the DIS) really take the dues into consideration when making an initial DVC purchase into SSR. IMHO the key thing that most potential purchasers focus on is the price per point: what it's going to cost them up front. Yes, it's short term thinking, but I confess that it took some fine posts here on the DIS to really drive home the true "cost" of dues over the 50 years of our ownership. But I feel that knocking $5/point off the price ("A savings of $1000 on your 200 point purchase, sir!") will be significantly more effective than a minor reduction in dues cost ("That's $3.12 per point instead of $3.48, sir!")
IMHO - YMMV
