I'd say this hurts people who exclusively own the X1. Less people will buy an X1, so it'll get less software support, period. It's not as if software sold on other platforms justifies developing for a platform your sales were not on. It's not a plus for these people and you'd be delusional to say so.
Otherwise it helps the devs, probably, depending on MS's personal support. Also helps PC gamers, and potentially everyone by not locking to a single system of DRM.
