I think you generalize the absurd US cellular carrier situation on to the world.
Most places in the world you have carriers which provides phone services, accessible by a SIM-card, and you have phones, which accepts SIM cards.
These are two entirely separate things which you choose entirely at your own bidding. You chose the carrier which provides you with a service matching your needs at a price you are willing to pay. And you use the SIM card they provide in the phone you have chosen entirely separate.
In a world like this a carrier doesn't "support" a phone. That would be like my ISP having to "support" my Dell PC, or me having to buy a PC from a limited selection offered by my ISP. It's an absurd position.
Most of the world does not work like the completely and fundamentally broken US cellphone market, and generalizing based on that is doomed to reap highly inaccurate results.
I may be generalizing incorrectly but given Mozilla's lack of comment either for or against the W3C DRM initiative I think they're not wanting to jeopardize partner arrangements by saying anything negative. Even if they have no deals requiring DRM, why turn off potential partners with statements that don't need to be made yet.
Usually they're publicly all over this sort of thing. I don't see any Mozilla people commenting in this thread about what they think either which is unusual but probably wise.
On the other hand I don't see statements from Opera either and they're usually pretty anti this sort of thing. Maybe they're both doing behind the scenes work to scuttle the DRM initiative and don't want to make it public yet.
