...would it really have made a difference?
Absolutely!
But, I honestly don't know if it would have been better or worse for them.
For me, I was hooked on the rules and edition philosophy/ideas leaks that were made prior to release. The end product ended up not being quite what I expected, and just isn't my cup of tea ... but I wasn't mislead (whether purposely or accidentally) by WotC by the leaks and previews.
However, the promises of features (DDI) that never appeared, the creation of the GSL (instead of remaining OGL), the pulling of pdf's and end of any support or occasional supplements for older editions, the sanctimonious and demeaning way they have treated requests and feedback from fans/customers, and the absolute boondoggling of most of their public relations attempts ... IMO adds up to, at worst, false advertising and straight up lying ... at best, absolute and inexcusable mismanagement.
If they had been honest and realistic about their abilities and what they would actually produce and release ... and had been up front about their intentions regarding the OGL and older edition materials ... I still would have bought the 4E core books, occasional supplements that I think I might be able to mine material from, occasional adventures, and most importantly - I would still be paying for a DDI subscription.
Because they didn't, I no longer purchase anything from them.
Whether I'm atypical in that regard, or whether a significant portion of WotC's possible customer base feel the same way, is the part open for conjecture.
But, I guess we'll never know what might have happened had WotC done the right thing instead.
