NOT every customer is important. Yes, there I said it.
I read an interesting article recently (though the article isn't that recent) that makes a good point. The ONLY important customers are those that are PAYING customers.
I'd modify that to be, the only important customers are those that WILL pay you money to purchase the goods you provide.
Those that pirate, or won't even consider buying anything you provide, and you wouldn't attract anyways...aren't important.
So, what you cater to are those that are buying your items, as well as the possible customers who are out there that you can entice to buy your products.
If you only cater to those that pirate your items and will never buy a single product from you, or hate your company so much that they won't buy anything from you...you aren't going to get any money.
I see WotC as trying to fullfill the first idea, of supporting the paying customer.
I see WotC trying to fullfill the second idea of creating products to bring in new paying customers (those who haven't bought anything yet, but can be attracted to buy items) with their Essentials incentives last year.
I see WotC failing miserably in other areas. Instead of continuing to create a better and easier access experience for those who would pay for such an experience with the DDI, PDFs, and electronic items, they instead are so worried about piracy and sharing that they alienate customers chasing away possible revenue instead of attracting it. Right now I see them on a maintaining schedule, one that maintains the current numbers, but doesn't really build on them in a significant manner (that's my OPINION by the way, not fact) that matters to Hasbro. Maintaining is a good thing...but if you glitch up in a way, it's easy to lose the balance and suddenly go into a deficit.
So, if you are a paying customer, I'd say you DO matter. If you hate 4e and state you'd refuse to ever buy anything from 4e, then as far as WoTC is concerned, I'd say paying attention to you would be a waste of time.
I think that WotC is actually paying MORE attention to you then you think though, and even those that hate 4e (waste of time in my opinion) are being paid attention to HEAVILY.
Edit: By the way the article I referred to is this...
