I think one negative consequence of their model is for new release, which will appear to lack features, compared to older games which have received years worth of DLCs; so buyers/players/complainers will complain that the new game lacks features compared to the previous games (adds some whining about dumbing down/decline too for good measure) and the devs are greedy *s who cut back features to sell as DLCs. Facing such reaction, the devs will double down on DLCs on existing titles, making the issue even worse in the long run...
