In a sense, this model makes things more accessible to everyone. For instance, now anybody can go to Gameservers.com and get their own dedi or cluster of dedis with just a few clicks and do what they want with them. Previously if I wanted to do that, I would have to rent a cabinet at a datacenter, set up a server box and maintain that box which is far more effort and money than the average Joe wants to spend on setting up a server for friends/clannies/mods/their own rules etc.
So yes, pretty much EVERYONE can get their own dedi easily and cheaply this way. However, what is different is that normally iGame/Wage/SGS would host and maintain the servers in their datacentres, in this case they would not have physical access to the server boxes. They can still moderate, mod and operate those dedis as they please though.
Black Ops is a obviously a special case though. Normally the server software for games is freely distributed, so you could choose to set up your own box or go with a game hosting provider, you only have option 2 with Black Ops.
