Mike Fricklas, Viacom's general counsel, said "We are delighted that Google appears to be stepping up to its responsibility and end the practice of infringement." However, he didn't comment on what, if any, effect the move would have on the infringement suit Viacom has been pursuing against YouTube for several months.
The lawyer for two other parties suing YouTube indicated that it won't have any affect on his clients' suits, saying "It does nothing about the past and won't be enough to protect the future."
