The subject title is a quote from the End of Greyhawk? thread.
I saw this and thought, well, sure, if there are enough customers who want things to change, write to WotC and tell them. Change your buying habits to not do business with a company that undertakes in practices you find undesireable (and note I don't mean immoral here - simply, if you don't like what a business is doing for whatever reason, then don't be a customer).
Tell them you won't subscribe to online. Tell them you won't buy more D&D unless they reverse this decision. Tell them you won't read their fiction, or buy miniatures, or Star Wars gaming stuff. Or just tell them nicely that as a customer you'd like the magazines back in print.
Anyone who really feels strongly about this could organize a writing campaign so that they get hundreds or thousands of requests at once, instead of one here and one there.
You could create a list of names that want things to change, or however you want to approach it.
In commerce, we vote with our dollars. And you also have more power in numbers.
I suppose you could even write to Hasbro's board of directors since their names are probably public record, and bring it to the top.
Personally, I don't think I'd be the person to lead such a crusade, but someone might want to undertake that if they feel strongly enough.
Just a suggestion.
