I don't normally take the time to read Freedom to Tinker, because it just gets me angry. This is no exception.

Not only will it protect Hollywood from the downside of the bill, it will also create new barriers to entry, making it harder for amateurs to create and distribute video content — and just at the moment when technology seems to be enabling high-quality amateur video distribution.

And this comment:

Who is a professional is a horrendous problem for reasons that nobody has mentioned yet: what about independent low budget filmakers? Will it be illegal to sell professional equipment to them because they “aren’t really professionals” or will they be chained down by rediculous DRM schemes?

This isn't only or even mostly about piracy, this is about stopping competition.
