For what reason? Are you going to watch 200 movies a day? It might just backfire, and we will not have a program.

The most important reason would be
the choice of what to watch - not only now, but also in the distant future, when all that downloaded contents will be long gone from the providers, maybe even along with the providers themselves ;)
About backfiring... I would say going from 100 to 200 would just be a blip on their radar. Going up to 2000 could be another thing though :)
