If summoner minions used DU, they wouldn't be used because they'd cost too much and attack slower and offer little new other than being able to move, which by itself isn't much of a compelling reason to use them. The only reason summoner is any good at all is because his stuff is extra.
Making a new character useful but not mandatory or excessively compelling is no easy feat. It has to be good enough that people will want to get it, or you'd never sell it, but if its even slightly beyond that, people will complained because they're "forced" to buy it.
The barbarian basically falls under the "not good enough" category, because the cases where he's actually desirable to have are very rare, and not really that relevant anymore. The jester is probably the closest to a perfect balance between doing something people would want without compelling people to buy it, because it does do useful things, but a lot of them require luck and are therefore unreliable in a tight situation.
However- if you're playing online, you can benefit from the DLC characters without owning them yourself. Thus, you're never truly forced to buy any of them, because you can just play with someone who chose to buy them.
