Pay them for access? Gleemax deal? I have no idea what you are talking about, and I think you don't have one either.
That said, both Hasbro and WotC are businesses. Without money (as in, the thing they make from selling what they produce), their employees don't get paid and then they as companies cease to exist. Would folks quit ragging on a company for keeping an eye on profit? It's not as if RPGs are a goldmine industry, even for the biggest player.
MSRD updates have been hinted at in the past, usually to include material found in closed sources like d20 Past and d20 Apocalypse. If any update is coming, it will probably be of that nature, and not a system update to bring Modern in line with our new 4e overlords. I may be wrong, but it's my best guess.
