Analogies suck, but look at (for example) Norton AntiVirus.  You pay
for a year of virus definition updates.  Then when the year runs out,
Symantec is not going to give you a single new virus definition even
if there's a new worm around that dwarfs Sobig, Klez and all the other
viruses put together ...  I can see brand C following a similar
strategy with their bogon updates.

[and that's not a new thing I guess - every single virus that comes
down the pike is written up in the press as the worst and most
virulent virus yet]
