From what I've been gathering, K/H is dumping most of its TSR-originated components. The publishing arm is going, aside from producing the necessary game books. DRAGON is already in other hands. AMAZING STORIES is dead again.
In fact, I just learned Jeff Grubb got the ax several months ago, which would explain why he never answered my emails.
The TSR situation seems to be exactly like what happened to another Wisconsin corporation, American Motors. There the owners scammed a boatload of money from a pro-big business Republican governor ("to stay in business"), used the capital to inflate its value, and sold themselves to Chrysler. Chrysler then demolished the company, fired most of the staff, and extracted the few things they wanted (in this case, the Jeep license, which ironically AMC had earlier taken from another company).
In this case, Lorraine Williams decided she'd made TSR valuable enough it was time to sell. WotC meanwhile were realizing that WotC was a single product company in desperate need to diversify their product base and possessing enough money to buy a product line. So.... WotC gives Williams a boatload of money and she vanishes from gaming. The acquisition of the AD&D line now makes WotC valuable enough to warrant attention from Hasbro/Kenner, who have been busy buying up once-big toy and game companies. H/K buys WotC/TSR and starts filleting it to recover the properties it wants (AD7D, Magic), selling off anything sellable (the magazines, the convention), and firing anyone they didn't feel like keeping (which is turning out to be most everyone).
Which explains why I'm seeing familiar names now appearing in other product lines and familiar product lines appearing under new names.
Which, assuming you're still awake, is why H/K is probably unlikely to care much about online reproductions of old articles. The current owners of the copyright are so far removed from the original material they may not be aware of or care about such matters.
