A lot of the major companies making pornographic videos are based in America. It is an industry worth over a billion dollars. This will affect some businesses. Vivid Video's emails, for instance, as well as Playboy.com's, are going to have to carry this. Note that there was an industry lawyer complaining already. Where there's lawyers, there's affected revenue streams.

It will raise the cost of doing business, and lower the profit margin. It's an incremental step forward.
