I would argue that if you don't think the Compendium, Character Builder, magazine content, and beta access are worth $6 a month, you're probably not the perfect target audience.
Actually, if the CB was worthwhile to my group (it's not, because of its inability to let you homebrew anything) I would resubscribe. If the magazines had a meaningful amount of content I would resubscribe. But I won't pay for a beta, and the Compendium is of limited usefulness to me since we don't have Internet access at the table. It's okay for prepping, but not compelling; I like to page through the books and read random bits as I look for just the right monster or seed for an adventure.
A good MB would sell me in a red hot second, but it has to be able to actually build monsters. Also, I have to be able to save or export them to my hard drive. Also, I need to be able to paste them in an Open Office document. If the MB doesn't accomplish these three things, it is essentially useless to me- I can't use it to make monsters for my adventures without it being more of a pain in the ass than it is to do them 'by hand'.
I say I'm their perfect target customer because I have an almost full collection of 4e books, am eager to spend what disposable income I have on products for my game and am
actively looking for a reason to resubscribe... and
god damn it, I can't find one. So instead I do stuff like buy colored pipe cleaners that we can use to make zones out of, or consider buying a mold so I can build some terrain. That $6 a month is a very tiny drop of cash, but
it has been about 9 months since I got my money's worth. (My sub expired in February.) I'm not willing to throw my money away or to reward a horrendous decrease in quality.
I suppose if DDI hadn't been doing so well, many people might be less outraged. I know that's part of the issue for me- a combination of misleading statements sometimes verging on outright lies coming from WotC since the Essentials update fiasco (which was actually a new CB entirely, one that basically didn't work at all at the time) and the replacement of quality tools, articles and content with seriously inferior quality and quantity.
For the same price. With very little sign of improvement- just a bunch more misleading statements about the new Monster Builder leading to
yet another round of disappointment.
Many many many of us keep saying the same thing:
Give it to us straight, WotC. Stop shoveling crap about how the new MB will build monsters when it won't. Stop sending us misleading information that just pisses everyone off. Good communication would go miles towards mollifying the customers you are driving away with this stuff.
