Yes, that's correct.

Quite simply, we've seen a significant rise in the number of cases of
people and companies using server based services as a method to stay
within the letter, but not the spirit, of the standard GPL. More
specifically, doing so in a commercial setting.

Switching to the Affero GPL gives us a little more leverage in dealing
with these cases.
